The New Economics of Hunger |

[P]rices for corn, soybeans, wheat, oats, rice and other grains began shooting through the roof... food [is] becoming the new gold.... For the 1 billion living on less than a dollar a day, it is a matter of survival. In a mud hut on the Sahara's edge, Manthita Sou, a 43-year-old widow in the Mauritanian desert village of Maghleg, is confronting wheat prices that are up 67 percent on local markets in the past year. Her solution: stop eating bread....
The root cause of price surges varies from crop to crop. But the crisis is being driven in part by an unprecedented linkage of the food chain.
A big reason for higher wheat prices, for instance, is the multiyear drought in Australia, something that scientists say may become persistent because of global warming. But wheat prices are also rising because U.S. farmers have been planting less of it, or moving wheat to less fertile ground. That is partly because they are planting more corn to capitalize on the biofuel frenzy.
This year, at least a fifth and perhaps a quarter of the U.S. corn crop will be fed to ethanol plants. A brutal convergence of events has hit an unprepared global market, and grain prices are sky high. The world's poor suffer most.Sunday, 27 April 2008; A01 | Washington Post by Anthony Faiola The globe's worst food crisis in a generation emerged as a blip on the big boards and computer screens of America's great grain exchanges. At first, it seemed like little more than a bout of bad weather.
In Chicago, Minneapolis and Kansas City, traders watched from the pits early last summer as wheat prices spiked amid mediocre harvests in the United States and Europe and signs of prolonged drought in Australia. But within a few weeks, the traders discerned an ominous snowball effect -- one that would eventually bring down a prime minister in Haiti, make more children in Mauritania go to bed hungry, even cause American executives at Sam's Club to restrict sales of large bags of rice.

Willie Nelson: Save Family Farms, Save America |
|
Posted by: doclalor on Thursday, April 27, 2006 - 07:18 AM |

[ Nelson argues that[i]f you care about local and democratic control, demand a Farm Bill that curbs the power of factory farms and the influence of lobbyists for large food corporations. If you care about health and nutrition for children, demand a Farm Bill that puts more fresh, wholesome food in our cities' schools. If you want your children and grandchildren to enjoy the benefits of a clean environment, demand a Farm Bill that increases protection of our natural resources by helping farmers transition to organic and more sustainable growing methods. As the editors of AlterNet point out, this article appeared in the Spring 2006 issue of Waterkeeper, the official magazine of Waterkeeper Alliance. --BL ]April 27, 2006 | AlterNetby Willie Nelson
As one of the founders of Farm Aid, I have watched with admiration and a good amount of satisfaction the growth of what many now call the "Good Food Movement" -- the growing interest in and demand for organic, humanely-raised and family farm-identified food that is transforming the way America grows its food and how our food gets to our tables. While it might seem obvious to many, good food comes from farms with healthy soil and clean water. I've always believed that the most important people on the planet are the ones who plant the seeds and care for the soil where they grow. As the stewards of the land, family farmers are the foundation of this movement, as well as its guarantor. No one can say they planted the original seed that gave rise to this movement, but many can claim they have helped nurture and cultivate its growth. Farm Aid's vision for America is to have many family farmers on the land -- a vision born out of our strong conviction that who grows our food and who cares for the land and water is of vital national importance; that farmers and their fields are the fabric that holds our country together. Many have asked me, "What is the Good Food movement?" The Good Food movement isn't just about good and delicious food -- although this is certainly one of its greatest achievements. The Good Food movement is at the center of some of the most important issues and debates that will define American society for years to come: issues like stewardship of our soil and water, local and democratic control of decision making and land use, health and nutrition and a thriving and sustainable food and farm economy needed to feed and fuel America.

How Much Fossil Fuel is in Your Food? |
|
Posted by: doclalor on Thursday, March 30, 2006 - 08:46 AM |
 |
23 March 2006 | Tom Dispatch.comThe blurb from Organic Consumers Assn's Organic Bytes letter runs: An average of over seven calories of fossil fuel is burned up for every calorie of energy we get from our food. This means that the average 2000 calorie daily diet requires approximately two quarts of crude oil to produce, process, package and transport.
The processing of just one pound of coffee requires over 8,000 calories of fossil-fuel energy -- the equivalent energy found in nearly 30 cubic feet of natural gas, or around two and a half pounds of coal.
To reduce the amount of fossil fuels consumed and greenhouse gases generated by the foods you eat, buy locally grown organic products, foods with minimal packaging, and avoid highly processed foods. --BLMy Saudi Arabian Breakfastby Chad Heeter
Please join me for breakfast. It's time to fuel up again.
On the table in my small Berkeley apartment this particular morning is a healthy looking little meal -- a bowl of imported McCann's Irish oatmeal topped with Cascadian Farms organic frozen raspberries, and a cup of Peet's Fair Trade Blend coffee. Like most of us, I prepare my breakfast at home and the ingredients for this one probably cost me about $1.25. (If I went to a caf? in downtown Berkeley, I'd likely have to add another $6.00, plus tip for the same.)
My breakfast fuels me up with about 400 calories, and it satisfies me. So, for just over a buck and half an hour spent reading the morning paper in my own kitchen, I'm energized for the next few hours. But before I put spoon to cereal, what if I consider this bowl of oatmeal porridge (to which I've just added a little butter, milk, and a shake of salt) from a different perspective. Say, a Saudi Arabian one.
Then, what you'd be likely to see -- what's really there, just hidden from our view (not to say our taste buds) -- is about four ounces of crude oil. Throw in those luscious red raspberries and that cup of java (another three ounces of crude), and don't forget those modest additions of butter, milk, and salt (another ounce), and you've got a tiny bit of the Middle East right here in my kitchen.
Now, let's drill a little deeper into this breakfast. Just where does this tiny gusher of oil actually come from? (We'll let this oil represent all fossil fuels in my breakfast, including natural gas and coal.)
Nearly 20% of this oil went into growing my raspberries on Chilean farms many thousands of miles away, those oats in the fields of County Kildare, Ireland, and that specially-raised coffee in Guatemala -- think tractors as well as petroleum-based fertilizers and pesticides.
The next 40% of my breakfast fossil-fuel equation is burned up between the fields and the grocery store in processing, packaging, and shipping.
Take that box of McCann's oatmeal. On it is an inviting image of pure, healthy goodness -- a bowl of porridge, topped by two peach slices. Scattered around the bowl are a handful of raw oats, what look to be four acorns, and three fresh raspberries. Those raw oats are actually a reminder that the flakes require a few steps twixt field and box. In fact, a visit to McCann's website illustrates each step in the cleaning, steaming, hulling, cutting, and rolling that turns the raw oats into edible flakes. Those five essential steps require significant energy costs.
Next, my oat flakes go into a plastic bag (made from oil), which is in turn inserted into an energy-intensive, pressed wood-pulp, printed paper box. Only then does my "breakfast" leave Ireland and travel over 5,000 fuel-gorging, CO2-emitting miles by ship and truck to my grocery store in California.
Coming from another hemisphere, my raspberries take an even longer fossil-fueled journey to my neighborhood. Though packaged in a plastic bag labeled Cascadian Farms (which perhaps hints at a birthplace in the good old Cascade mountains of northwest Washington), the small print on the back, stamped "A Product of Chile," tells all -- and what it speaks of is a 5,800-mile journey to Northern California.
If you've been adding up percentages along the way, perhaps you've noticed that a few tablespoons of crude oil in my bowl have not been accounted for. That final 40% of the fossil fuel in my breakfast is used up by the simple acts of keeping food fresh and then preparing it. In home kitchens and restaurants, the chilling in refrigerators and the cooking on stoves using electricity or natural gas gobbles up more energy than you might imagine.
For decades, scientists have calculated how much fossil fuel goes into our food by measuring the amount of energy consumed in growing, packing, shipping, consuming, and finally disposing of it. The "caloric input" of fossil fuel is then compared to the energy available in the edible product, the "caloric output."
What they've discovered is astonishing. According to researchers at the University of Michigan's Center for Sustainable Agriculture, an average of over seven calories of fossil fuel is burned up for every calorie of energy we get from our food. This means that in eating my 400 calorie breakfast, I will, in effect, have "consumed" 2,800 calories of fossil-fuel energy. (Some researchers claim the ratio to be as high as ten to one.)
But this is only an average. My cup of coffee gives me only a few calories of energy, but to process just one pound of coffee requires over 8,000 calories of fossil-fuel energy -- the equivalent energy found in nearly a quart of crude oil, 30 cubic feet of natural gas, or around two and a half pounds of coal.
So how do you gauge how much oil went into your food?
First check out how far it traveled. The further it traveled, the more oil it required. Next, gauge how much processing went into the food. A fresh apple is not processed, but Kellogg's Apple Jacks cereal requires enormous amounts of energy to process. The more processed the food, the more oil it required. Then consider how much packaging is wrapped around your food. Buy fresh vegetables instead of canned, and buy bulk beans, grains, and flour if you want to reduce that packaging.
By now, you're thinking that you're in the clear, because you eat strictly organically-grown foods. When it comes to fossil-fuel calculations though, the manner in which food's grown is where differences stop. Whether conventionally-grown or organically-grown, a raspberry is shipped, packed, and chilled the same way.
Yes, there are some savings from growing organically, but possibly only of a slight nature. According to a study by David Pimentel at Cornell University, 30% of fossil-fuel expenditure on farms growing conventional (non-organic) crops is found in chemical fertilizer. This 30% is not consumed on organic farms, but only if the manure used as fertilizer is produced in very close proximity to the farm. Manure is a heavy, bulky product. If farms have to truck bulk manure for any distance over a few miles, the savings are eaten up in diesel-fuel consumption, according to Pimentel. One source of manure for organic farmers in California is the chicken producer Foster Farms. Organic farmers in Monterey County, for example, will have to truck tons of Foster's manure from their main plant in Livingston, Ca. to fields over one hundred miles away.
So the next time we're at the grocer, do we now have to ask not only where and how this product was grown, but how far its manure was shipped?
Well, if you're in New York City picking out a California-grown tomato that was fertilized with organic compost made from kelp shipped from Nova Scotia, maybe it's not such a bad question. But should we give up on organic? If you're buying organic raspberries from Chile each week, then yes. The fuel cost is too great, as is the production of the greenhouse gases along with it. Buying locally-grown foods should be the first priority when it comes to saving fossil fuel.
But if there were really truth in packaging, on the back of my oatmeal box where it now tells me how many calories I get from each serving, it would also tell me how many calories of fossil fuels went into this product. On a scale from one to five -- with one being non-processed, locally-grown products and five being processed, packaged imports -- we could quickly average the numbers in our shopping cart to get a sense of the ecological footprint of our diet. From this we would gain a truer sense of the miles-per-gallon in our food.
What appeared to be a simple, healthy meal of oatmeal, berries, and coffee looks different now. I thought I was essentially driving a Toyota Prius hybrid -- by having a very fuel-efficient breakfast, but by the end of the week I've still eaten the equivalent of over two quarts of Valvoline. From the perspective of fossil-fuel consumption, I now look at my breakfast as a waste of precious resources. And what about the mornings that I head to Denny's for a Grand-Slam breakfast: eggs, pancakes, bacon, sausage? On those mornings -- forget about fuel efficiency -- I'm driving a Hummer.
What I eat for breakfast connects me to the planet, deep into its past with the fossilized remains of plants and animals which are now fuel, as well as into its future, when these non-renewable resources will likely be in scant supply. Maybe these thoughts are too grand to be having over breakfast, but I'm not the only one on the planet eating this morning. My meal traveled thousands of miles around the world to reach my plate. But then there's the rise of perhaps 600 million middle-class Indians and Chinese. They're already demanding the convenience of packaged meals and the taste of foreign flavors. What happens when middle-class families in India or China decide they want their Irish oats for breakfast, topped by organic raspberries from Chile? They'll dip more and more into the planet's communal oil well. And someday soon, we'll all suck it dry.
Chad Heeter grew up eating fossil fuels in Lee's Summit, Missouri. He's a freelance writer, documentary filmmaker, and a former high school science teacher.

Sweden Plans to Be World's First Oil-Free Economy |
|
Posted by: doclalor on Thursday, February 09, 2006 - 09:27 AM |
 |
[ This piece about Sweden's commitment to convert to fossil-free fuels shames the rest of the developed world. Sure, Sweden's got ethanol on the table as a possible part of its strategy, contra voices of sanity (like that of James Howard Kunstler), insight (like that of Richard Manning), and manifesto (like the editors of The Stranger, who call for real solutions). But at least Sweden is treating the issue of sustainable energy policy as urgent. --BL ] 8 Feb 2006 | The Guardian
? 15-year limit set for switch to renewable energy
? Biofuels favoured over further nuclear power
by John Vidal
Sweden is to take the biggest energy step of any advanced western economy by trying to wean itself off oil completely within 15 years - without building a new generation of nuclear power stations.
The attempt by the country of 9 million people to become the world's first practically oil-free economy is being planned by a committee of industrialists, academics, farmers, car makers, civil servants and others, who will report to parliament in several months.
The intention, the Swedish government said yesterday, is to replace all fossil fuels with renewables before climate change destroys economies and growing oil scarcity leads to huge new price rises.
"Our dependency on oil should be broken by 2020," said Mona Sahlin, minister of sustainable development. "There shall always be better alternatives to oil, which means no house should need oil for heating, and no driver should need to turn solely to gasoline."
According to the energy committee of the Royal Swedish Academy of Sciences, there is growing concern that global oil supplies are peaking and will shortly dwindle, and that a global economic recession could result from high oil prices.
Ms Sahlin has described oil dependency as one of the greatest problems facing the world. "A Sweden free of fossil fuels would give us enormous advantages, not least by reducing the impact from fluctuations in oil prices," she said. "The price of oil has tripled since 1996."
A government official said: "We want to be both mentally and technically prepared for a world without oil. The plan is a response to global climate change, rising petroleum prices and warnings by some experts that the world may soon be running out of oil."
Sweden, which was badly hit by the oil price rises in the 1970s, now gets almost all its electricity from nuclear and hydroelectric power, and relies on fossil fuels mainly for transport. Almost all its heating has been converted in the past decade to schemes which distribute steam or hot water generated by geothermal energy or waste heat. A 1980 referendum decided that nuclear power should be phased out, but this has still not been finalised.
The decision to abandon oil puts Sweden at the top of the world green league table. Iceland hopes by 2050 to power all its cars and boats with hydrogen made from electricity drawn from renewable resources, and Brazil intends to power 80% of its transport fleet with ethanol derived mainly from sugar cane within five years.
Last week George Bush surprised analysts by saying that the US was addicted to oil and should greatly reduce imports from the Middle East. The US now plans a large increase in nuclear power.
The British government, which is committed to generating 10% of its electricity from renewable sources by 2012, last month launched an energy review which has a specific remit to consider a large increase in nuclear power. But a report by accountants Ernst & Young yesterday said that the UK was falling behind in its attempt to meet its renewables target.
"The UK has Europe's best wind, wave and tidal resources yet it continues to miss out on its economic potential," said Jonathan Johns, head of renewable energy at Ernst & Young.
Energy ministry officials in Sweden said they expected the oil committee to recommend further development of biofuels derived from its massive forests, and by expanding other renewable energies such as wind and wave power.
Sweden has a head start over most countries. In 2003, 26% of all the energy consumed came from renewable sources - the EU average is 6%. Only 32% of the energy came from oil - down from 77% in 1970.
The Swedish government is working with carmakers Saab and Volvo to develop cars and lorries that burn ethanol and other biofuels. Last year the Swedish energy agency said it planned to get the public sector to move out of oil. Its health and library services are being given grants to convert from oil use and homeowners are being encouraged with green taxes. The paper and pulp industries use bark to produce energy, and sawmills burn wood chips and sawdust to generate power.

Gas Guzzling Food: The SUV in the Pantry |

grabbed from Sustainable Business.com on 1 Dec. 2005
by Thomas Starrs
I spend a fair amount of time thinking about how to reduce my family's dependence on energy, particularly energy derived from fossil fuels. I commute to work by bicycle or bus, install compact fluorescents when light bulbs burn out, replace major appliances with the most efficient ones I can afford, and cast jealous glances at my friends who drive hybrids or alternative-fueled vehicles. But until recently, I didn't think of myself as an energy glutton because of the food I eat.
Then I read an astonishing statistic: It takes about 10 fossil fuel calories to produce each food calorie in the average American diet. So if your daily food intake is 2,000 calories, then it took 20,000 calories to grow that food and get it to you. In more familiar units, this means that growing, processing and delivering the food consumed by a family of four each year requires the equivalent of almost 34,000 kilowatt-hours (kWh) of energy, or more than 930 gallons of gasoline (for comparison, the average U.S. household annually consumes about 10,800 kWh of electricity, or about 1,070 gallons of gasoline).
In other words, we use about as much energy to grow our food as to power our homes or fuel our cars.

One Roof at a Time |

November/December 2004 | Mother Jones
by Bill McKibben
With no help from the Bush administration -- but plenty from Europe, Japan, New York, and California -- solar power is edging into the mainstream.
If you're like most Americans, you've spent your life invisibly attached to an electric meter. When you wake up and switch on the light, you nudge it forward a little faster. When you toast bread, watch TV, open the fridge, flick on the computer, you push its pace. For all practical purposes, it only goes one way.
But in the last few years, a small but quickly growing band of Americans have found out that you can make the meter spin backward. These are not the off-the-grid, back-to-the-land, composting-privy sorts who pioneered the renewable energy movement in its early days. No, these are suburbanites (and city and small-town dwellers) who are installing photovoltaic (PV) systems on their roofs -- systems that tie directly into the power grid. They buy power from the local utility, just like always. But when the sun comes out, they are the local utility, pulling electrons from the sun and pushing the extra out to the grid.

Proctor & Gamble ?Buzz Marketing? Unit Hit With Complaint |
|
Posted by: doclalor on Sunday, October 30, 2005 - 08:28 AM |
 |
19 Oct. 2005 | USA Today
by Bruce Horovitz
Is Procter & Gamble ? the world's biggest packaged goods marketer ? breaking the law by enlisting teens to coax friends to try teen-tailored products?
One consumer advocacy group thinks it is. Commercial Alert on Tuesday filed a complaint with the Federal Trade Commission that says P&G's word-of-mouth marketing unit, Tremor, targets teens with deceptive advertising.
If successful, the complaint would have broad impact on the ad business. So-called buzz marketing is the industry's hottest trend. More than 85% of the nation's top 1,000 marketers now use some form, estimates Marian Salzman, trend-spotter at JWT Worldwide.
Advertising Age estimates buzz marketing to be a $100 million to $150 million industry. Though still relatively small in dollar volume, the provocative practice ranks among marketing's highest growth areas ? and is causing genuine angst within the industry.
"This is a practice that may be illegal," says Jonah Bloom, executive editor of Advertising Age. "It's probably only a matter of time before someone jumps on it" to stop it, he says.
Which is what Commercial Alert is trying to do. P&G, and several smaller buzz marketing specialists named in its complaint, "are perpetuating large-scale deception upon consumers" when people they recruit to promote products by word of mouth don't disclose that fact, says Gary Ruskin, executive director of Commercial Alert.
FTC officials declined to comment.
P&G's 4-year-old Tremor division has a panel of 250,000 teens ages 13 to 19 who are asked to talk with friends about new products or concepts P&G sends them. About 75% of members are female.
Steve Knox, CEO of Tremor, which works for outside clients as well as parent P&G, had no comment on the complaint. But, he says, "We're an incredibly ethical company." Panelists are not paid cash, he says, but get product samples or other materials.
"To be a member is empowering for a teen," says Knox. "You have a voice that will be heard, and you get cool information before your friends receive it."
Knox won't name any of Tremor's outside clients, citing client confidentiality.
Tremor recently did a campaign for P&G's Clairol Herbal Essences. The purpose was to help teens feel more comfortable about coloring hair. It sent some members cardboard booklets that let them push locks of their own hair through a hole and compare it with what the hair would look like in a new color.
"If we've done our work correctly, they talk to their friends about it," says Knox. Tremor doesn't tell members to say they are part of Tremor, he says, "because you never tell a (panelist) what to say."
Ruskin says that's bogus. At a minimum, his complaint says, the FTC should "issue subpoenas" to P&G executives at Tremor ? and other buzz marketers ? to determine whether their endorsers are disclosing that they are paid marketers.

Solar Cell Panels Made out of Everyday Plastics |
|
Posted by: doclalor on Tuesday, October 11, 2005 - 07:38 AM |
 |
[ From the piece:Made of a single layer of plastic sandwiched between two conductive electrodes, UCLA's solar cell is easy to mass-produce and costs much less to make - roughly one-third of the cost of traditional silicon solar technology.... "We hope that ultimately solar energy can be extensively used in the commercial sector as well as the private sector. Imagine solar cells installed in cars to absorb solar energy to replace the traditional use of diesel and gas. People will vie to park their cars on the top level of parking garages so their cars can be charged under sunlight. Using the same principle, cell phones can also be charged by solar energy," Yang said. "There are such a wide variety of applications." --BL ] 10 October 2005 | AZoM.com
With oil and gas prices in the United States hovering at an all-time high, interest in renewable energy alternatives is again heating up. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science hope to meet the growing demand with a new and more affordable way to harness the sun's rays: using solar cell panels made out of everyday plastics.
In research published in Nature Materials magazine, UCLA engineering professor Yang Yang, postdoctoral researcher Gang Li and graduate student Vishal Shrotriya showcase their work on an innovative new plastic (or polymer) solar cell they hope eventually can be produced at a mere 10 percent to 20 percent of the current cost of traditional cells, making the technology more widely available.
"Solar energy is a clean alternative energy source. It's clear, given the current energy crisis, that we need to embrace new sources of renewable energy that are good for our planet. I believe very strongly in using technology to provide affordable options that all consumers can put into practice," Yang said.

Organic farming produces same corn and soybean yields as conventional farms, but consumes less energy and no pesticides, study finds Susan S. Lang Cornell University, July 13, 2005 [via agnet]
ITHACA, N.Y. -- Organic farming produces the same yields of corn and soybeans as does conventional farming, but uses 30 percent less energy, less water and no pesticides, a review of a 22-year farming trial study concludes.
David Pimentel, a Cornell University professor of ecology and agriculture, concludes, "Organic farming offers real advantages for such crops as corn and soybeans." Pimentel is the lead author of a study that is published in the July issue of Bioscience (Vol. 55:7) analyzing the environmental, energy and economic costs and benefits of growing soybeans and corn organically versus conventionally. The study is a review of the Rodale Institute Farming Systems Trial, the longest running comparison of organic vs. conventional farming in the United States.

Toxic Contaminant Levels in Farmed and Wild-Caught Salmon Species |
|
Posted by: doclalor on Monday, March 21, 2005 - 03:43 PM |
 |
PHYSICIANS FOR SOCIAL RESPONSIBILITY, accessed 21 March 2005 through their http://www.mercuryaction.org website
Recent studies surveying contaminant levels in farmed and
wild-caught salmon have shown that, on average, farmed salmon contain
substantially higher concentrations of a variety of persistent organic
contaminants such as PCBs, dioxins, and pesticides. These studies
indicate that wild salmon, being generally lower in toxic contaminants, is a
healthier choice for consumers. However, closer inspection reveals that
contaminant levels in individual fish can vary widely across wild and farmed
salmon of various species and from various geographic regions, so the issue is
not black and white.

Five A Day For Fish? Veggie-Eating Creatures Healthier For Humans |
|

4 March 2004 | Scripps Howard News Service
by Joan Lowy
You are what you eat, even if you're a fish. And fish that thrive on veggies tend to be less toxic than flesh eaters.
With new studies showing PCBs, dioxin, and pesticides in salmon and mercury in canned tuna, consumers who find themselves struggling to figure out what's safe to eat will find some species of fish are high in contaminants, while others are generally low.
The reason is usually diet -- some fish eat smaller fish, but other fish eat veggies and tiny organisms.

ALERT:
NEW EPA DEAL LETS FACTORY FARMS POLLUTE AIR WITHOUT RESTRICTION
The day after the inauguration, January 21, the Bush Administration
signed an agreement that allows factory farms to freely violate
any and all clean air standards for the next two years, and forgives
these same companies from paying fines for past air pollution violations.
In exchange for the freedom to pollute without any restrictions,
the deal "requests" that factory farms agree to monitor
their air pollution and provide that data to the government. Bush's
"Dirty Air" agreement is outrageous, given that the Clean
Air Act already requires factory farms to provide air pollution
data, while also requiring facilities to adhere to clean air standards.
One of the companies that will benefit the most from this arrangement
with the Bush Administration is Tyson Foods, who also happened to
be one of the largest donors to the Bush inaugural festivities.
Fortunately there is a 30 day public comment period. Please make
your voice heard. Take action here. http://www.organicconsumers.org/epa3.htm

LAUNCHES NEW CAMPAIGN TO PROMOTE "HEALTHIER" JUNK FOOD
IN SCHOOLS
In response to efforts to rid schools of junk food, the Vending
Association has launched a new marketing campaign using color-coded
stickers to indicate to children the relative "healthiness"
of the vending machine snack. A red sticker indicates the snack
should only be chosen rarely, yellow is "choose occasionally,"
and green means the snack is healthy and should be chosen frequently.
An example of a snack that will receive a green sticker is Teddy
Grahams, a product that comes in varieties such as sugared cinnamon,
chocolate, and creme-filled. The Vending Association announced this
new campaign with a press conference, urging parents and children
to exercise more frequently by doing sit-ups and push-ups during
TV commercials. Learn

THICKBURGERS, WAL-MART, & COKE: THE 10 WORST CORPORATIONS OF
2004 
The Multinational Monitor has released its annual list of the "10
Worst Corporations of 2004." Among the "winners"
of this prestigious award are Coca-Cola, Wal-Mart and Hardees. Coca-Cola
made the list when documentation surfaced revealing the company
was involved in 179 human rights violations at its bottling plants
in Columbia, including allegations of involvement in nine murders
of union leaders. Wal-Mart was caught manipulating the tax system
in order maximize profits at the expense of taxpayers. In fact,
it turns out that each of Wal-Mart's 1000+ stores are costing taxpayers
nearly half a million dollars per year. Hardees made its debut on
the "Worst Corporations" list for its overtly aggressive
advertising of its new product, the "Monster Thickburger."
The 2/3 pound sandwich is 1,420 calories and equivalent to eating
five standard sized hamburgers. Learn

Company spent $260,000 lobbying for herbicideOct. 27, 2004 | Associated Press
by FREDERIC J. FROMMER
WASHINGTON - The manufacturer of a herbicide that has been linked to frog
deformities has spent $260,000 lobbying the Environmental Protection Agency
and other government officials, an Associated Press review of disclosure
forms shows.
Syngenta Crop Protection, which makes the herbicide atrazine, enlisted
former Senate Majority Leader Bob Dole to meet with White House officials on
at least one occasion. Dole represents the U.S. affiliate of Swiss-based
Syngenta as well as the Kansas Corn Growers.

16 Nov. 2004 | Organic Consumers Association Study Launch Date Suspended Until Early 2005 Offers Public Comment Period
The Environmental Protection Agency (EPA), led by Bush appointees, is seeking input on a new proposed study in which infants in participating low income families will be monitored for health impacts as they undergo exposure to known toxic chemicals over the course of two years. The study entitled Children?s Environmental Exposure Research Study (CHEERS) will look at how chemicals can be ingested, inhaled or absorbed by children ranging from babies to 3 years old.
For taking part in these studies, each family will receive $970, a free video camera, a T-shirt, and a framed certificate of appreciation.
In October, the EPA received $2.1 million to do the study from the American Chemistry Council, a chemical industry front group that includes members such as Dow, Exxon, and Monsanto (see full list of members on OCA site). Critics of the research, including some EPA scientists, claim the study's funders guarantee the results will be biased in favor of the chemical industry, at the expense of the health of the impoverished children serving as test subjects.

[ Oil reserves elsewhere are not what they once were ...It is not easy and it is not cheap, and through most of the 1980's and 1990's, it was not attractive to pursue, because there was plenty of crude oil available from more convenient sources and the market price was too low to reward large-scale tar sands development.

A visionary biologist says mushrooms are potent antiviral and antibacterial agents, as well as key boosters to the human immune system. They also might end up saving the Earth.
by Kelly Hearn, AlterNet
To lots of folks, a middle-aged man who says mushrooms can save the world falls into the category of turbo-freak. But to some environmentalists, scientists and major investors, Paul Stamets is the trippiest of profitable kings.
"Mushrooms restore health both on the personal and ecological level," says Stamets, mycologist and owner of Fungi Perfecti, a family-owned mushroom business in Shelton, Wash. "Mushrooms can heal people and the planet."

Mercury in many lakes, rivers |
|

24 August 2004 | USA TODAY
by Elizabeth Weise and Traci Watson
One third of the nation's lake waters and one-quarter of its riverways are contaminated with mercury and other pollutants that could cause health problems for children and pregnant women who eat too much fish, the Environmental Protection Agency said Tuesday.
States issued warnings for mercury and other pollutants in 2003 for nearly 850,000 miles of U.S. rivers ? a 65% increase over 2002 ? and 14 million acres of lakes. The warning level is the highest ever reported by the EPA. It is partly a result of states taking a more aggressive role in monitoring for mercury, according to environmental officials.
The warnings do not apply to fish caught in the deep seas that are sold in stores and restaurants. An extremely small percentage of commercially sold fish come from inland lakes and rivers.

Disasters spawned by global warming are no longer science fiction, Ross Gelbspan argues in "Boiling Point" -- they're already here.
by Katharine Mieszkowski
In Scotland, hundreds of thousands of arctic terns, kittiwakes, guillemots and great skuas suddenly aren't having any babies. The culprit? Global warming has disrupted their food supply, according to the Royal Society for the Protection of Birds.
The seabirds feed primarily on sandeels, a small silvery fish that once teemed along the northern Scotland seashore. But changes in sea temperature and currents caused by the heating up of the earth's atmosphere are causing the plankton that the sandeels eat to move north, leaving no fish for the birds to eat. One bird monitor who has spent some three decades counting breeding pairs and chicks at the Scottish nesting site called the sudden failure of the seabirds to reproduce simply "unprecedented in Europe."

Dupont Denies Poisoning Consumers with Teflon Products |

DuPont, Now in the Frying Pan8 August 2004 | New York Times
by AMY CORTESE
TEFLON has been hugely successful for DuPont, which over the last half-century has made the material almost ubiquitous, putting it not just on frying pans but also on carpets, fast-food packaging, clothing, eyeglasses and electrical wires - even the fabric roofs covering football stadiums.
Now DuPont has to worry that Teflon and the materials used to make it have perhaps become a bit too ubiquitous. Teflon constituents have found their way into rivers, soil, wild animals and humans, the company, government environmental officials and others say. Evidence suggests that some of the materials, known to cause cancer and other problems in animals, may be making people sick.
While it remains one of DuPont's most valuable assets, Teflon has also become a potentially huge liability. The Environmental Protection Agency filed a complaint last month charging the company with withholding evidence of its own health and environmental concerns about an important chemical used to manufacture Teflon. That would be a violation of federal environmental law, compounded by the possibility that DuPont covered up the evidence for two decades.

Subway: Junk Food, Junk Economy |

13 July 2004 | OrganicConsumers.org
by Russell Mokhiber and Robert Weissman
The American Heart Association's (AHA) recommendations are revered as pure fact by doctors and patients alike. But as is the case in most sects of the U.S. government, a public institution's policies can also be heavily swayed by corporate dollars. As an example, AHA only endorses Bayer aspirin, and in return, Bayer "donates" $500,000 to AHA every year. Since 2002, Subway has also been riding the AHA bandwagon.. In exchange for $10 million in "donations" over the course of 5 years to AHA, Subway can proudly plaster the AHA's "fighting heart disease and strokes" logo on its advertising materials. Although the majority of the food sold at Subway outlets includes junk food, processed red meats and cheeses, chips, soda, and cookies, thanks to creative advertising and the AHA, the majority of Americans mistakenly equate Subway with a healthy fast food outlet. Subway now has more stores in the U.S. than McDonalds (an average of over 300 in every state) with 21,528 restaurants in 75 countries.

The EPA and two doctors' groups have issued strong warnings about the dangers of eating mercury-laced fish. Then why is the White House working to loosen restrictions on mercury emissions from coal-burning power plants?
by Sharon Lerner
Remember when fish was the healthy choice? Today, the pluses of seafood -- being low in saturated fat and high in omega-3 oils -- are offset by creepy mounting knowledge about how much pollution has become a part of most fish flesh. And, just when you may have been getting a handle on which fish are safe to eat, the seascape has once again shifted.
Updated federal guidelines released in March lowered the amount of albacore that pregnant women, nursing mothers and young children should consume in a week to one six-ounce serving. Now two groups have come out with their own set of more stringent rules about eating fish.

Global Population to Level Off? |
|
Posted by: doclalor on Thursday, May 27, 2004 - 10:47 AM |
 |
[ Environmental author Bill McKibben argues that global population may peak within a generation: We've increased the population fourfold in that 150 years; the amount of food we grow has gone up faster still; the size of our economy has quite simply exploded.
But now -- now may be the special time. So special that in the Western world we might each of us consider, among many other things, having only one child -- that is, reproducing at a rate as low as that at which human beings have ever voluntarily reproduced. Is this really necessary? Are we finally running up against some limits?
To try to answer this question, we need to ask another: How many of us will there be in the near future? Here is a piece of news that may alter the way we see the planet -- an indication that we live at a special moment. At least at first blush the news is hopeful. New demographic evidence shows that it is at least possible that a child born today will live long enough to see the peak of human population.....
United Nations analysts offer as their mid-range projection that it will top out at 10 to 11 billion, up from just under six billion at the moment. The world is still growing, at nearly a record pace -- we add a New York City every month, almost a Mexico every year, almost an India every decade. But the rate of growth is slowing; it is no longer "exponential," "unstoppable," "inexorable," "unchecked," "cancerous." If current trends hold, the world's population will all but stop growing before the twenty-first century is out.
--BL ] A Special Moment in HistoryThe fate of our planet will be determined in the next few decades, through our technological, lifestyle, and population choices
May 1998 | The Atlantic Monthly
by Bill McKibbenPart I (of III)BEWARE of people preaching that we live in special times. People have preached that message before, and those who listened sold their furniture and climbed up on rooftops to await ascension, or built boats to float out the coming flood, or laced up their Nikes and poisoned themselves in some California subdivision. These prophets are the ones with visions of the seven-headed beast, with a taste for the hair shirt and the scourge, with twirling eyes. No, better by far to listen to Ecclesiastes, the original wise preacher, jaded after a thousand messiahs and a thousand revivals.One generation passes away, and another generation comes; but the earth abides forever.... That which has been is what will be, that which is done is what will be done, and there is nothing new under the sun. Is there anything of which it may be said, "See, this is new"? It has already been in ancient times before us. And yet, for all that, we may live in a special time. We may live in the strangest, most thoroughly different moment since human beings took up farming, 10,000 years ago, and time more or less commenced. Since then time has flowed in one direction -- toward more, which we have taken to be progress. At first the momentum was gradual, almost imperceptible, checked by wars and the Dark Ages and plagues and taboos; but in recent centuries it has accelerated, the curve of every graph steepening like the Himalayas rising from the Asian steppe. We have climbed quite high. Of course, fifty years ago one could have said the same thing, and fifty years before that, and fifty years before that. But in each case it would have been premature. We've increased the population fourfold in that 150 years; the amount of food we grow has gone up faster still; the size of our economy has quite simply exploded.
But now -- now may be the special time. So special that in the Western world we might each of us consider, among many other things, having only one child -- that is, reproducing at a rate as low as that at which human beings have ever voluntarily reproduced. Is this really necessary? Are we finally running up against some limits?
To try to answer this question, we need to ask another: How many of us will there be in the near future? Here is a piece of news that may alter the way we see the planet -- an indication that we live at a special moment. At least at first blush the news is hopeful. New demographic evidence shows that it is at least possible that a child born today will live long enough to see the peak of human population.
Around the world people are choosing to have fewer and fewer children -- not just in China, where the government forces it on them, but in almost every nation outside the poorest parts of Africa. Population growth rates are lower than they have been at any time since the Second World War. In the past three decades the average woman in the developing world, excluding China, has gone from bearing six children to bearing four. Even in Bangladesh the average has fallen from six to fewer than four; even in the mullahs' Iran it has dropped by four children. If this keeps up, the population of the world will not quite double again; United Nations analysts offer as their mid-range projection that it will top out at 10 to 11 billion, up from just under six billion at the moment. The world is still growing, at nearly a record pace -- we add a New York City every month, almost a Mexico every year, almost an India every decade. But the rate of growth is slowing; it is no longer "exponential," "unstoppable," "inexorable," "unchecked," "cancerous." If current trends hold, the world's population will all but stop growing before the twenty-first century is out.
And that will be none too soon. There is no way we could keep going as we have been. The increase in human population in the 1990s has exceeded the total population in 1600. The population has grown more since 1950 than it did during the previous four million years. The reasons for our recent rapid growth are pretty clear. Although the Industrial Revolution speeded historical growth rates considerably, it was really the public-health revolution, and its spread to the Third World at the end of the Second World War, that set us galloping. Vaccines and antibiotics came all at once, and right behind came population. In Sri Lanka in the late 1940s life expectancy was rising at least a year every twelve months. How much difference did this make? Consider the United States: if people died throughout this century at the same rate as they did at its beginning, America's population would be 140 million, not 270 million.
If it is relatively easy to explain why populations grew so fast after the Second World War, it is much harder to explain why the growth is now slowing. Experts confidently supply answers, some of them contradictory: "Development is the best contraceptive" -- or education, or the empowerment of women, or hard times that force families to postpone having children. For each example there is a counterexample. Ninety-seven percent of women in the Arab sheikhdom of Oman know about contraception, and yet they average more than six children apiece. Turks have used contraception at about the same rate as the Japanese, but their birth rate is twice as high. And so on. It is not AIDS that will slow population growth, except in a few African countries. It is not horrors like the civil war in Rwanda, which claimed half a million lives -- a loss the planet can make up for in two days. All that matters is how often individual men and women decide that they want to reproduce.
Will the drop continue? It had better. UN mid-range projections assume that women in the developing world will soon average two children apiece -- the rate at which population growth stabilizes. If fertility remained at current levels, the population would reach the absurd figure of 296 billion in just 150 years. Even if it dropped to 2.5 children per woman and then stopped falling, the population would still reach 28 billion.
But let's trust that this time the demographers have got it right. Let's trust that we have rounded the turn and we're in the home stretch. Let's trust that the planet's population really will double only one more time. Even so, this is a case of good news, bad news. The good news is that we won't grow forever. The bad news is that there are six billion of us already, a number the world strains to support. One more near-doubling -- four or five billion more people -- will nearly double that strain. Will these be the five billion straws that break the camel's back?
Big Questions
WE'VE answered the question How many of us will there be? But to figure out how near we are to any limits, we need to ask something else: How big are we? This is not so simple. Not only do we vary greatly in how much food and energy and water and minerals we consume, but each of us varies over time. William Catton, who was a sociologist at Washington State University before his retirement, once tried to calculate the amount of energy human beings use each day. In hunter-gatherer times it was about 2,500 calories, all of it food. That is the daily energy intake of a common dolphin. A modern human being uses 31,000 calories a day, most of it in the form of fossil fuel. That is the intake of a pilot whale. And the average American uses six times that -- as much as a sperm whale. We have become, in other words, different from the people we used to be. Not kinder or unkinder, not deeper or stupider -- our natures seem to have changed little since Homer. We've just gotten bigger. We appear to be the same species, with stomachs of the same size, but we aren't. It's as if each of us were trailing a big Macy's-parade balloon around, feeding it constantly.
So it doesn't do much good to stare idly out the window of your 737 as you fly from New York to Los Angeles and see that there's plenty of empty space down there. Sure enough, you could crowd lots more people into the nation or onto the planet. The entire world population could fit into Texas, and each person could have an area equal to the floor space of a typical U.S. home. If people were willing to stand, everyone on earth could fit comfortably into half of Rhode Island. Holland is crowded and is doing just fine.
But this ignores the balloons above our heads, our hungry shadow selves, our sperm-whale appetites. As soon as we started farming, we started setting aside extra land to support ourselves. Now each of us needs not only a little plot of cropland and a little pasture for the meat we eat but also a little forest for timber and paper, a little mine, a little oil well. Giants have big feet. Some scientists in Vancouver tried to calculate one such "footprint" and found that although 1.7 million people lived on a million acres surrounding their city, those people required 21.5 million acres of land to support them -- wheat fields in Alberta, oil fields in Saudi Arabia, tomato fields in California. People in Manhattan are as dependent on faraway resources as people on the Mir space station.
Those balloons above our heads can shrink or grow, depending on how we choose to live. All over the earth people who were once tiny are suddenly growing like Alice when she ate the cake. In China per capita income has doubled since the early 1980s. People there, though still Lilliputian in comparison with us, are twice their former size. They eat much higher on the food chain, understandably, than they used to: China slaughters more pigs than any other nation, and it takes four pounds of grain to produce one pound of pork. When, a decade ago, the United Nations examined sustainable development, it issued a report saying that the economies of the developing countries needed to be five to ten times as large to move poor people to an acceptable standard of living -- with all that this would mean in terms of demands on oil wells and forests.
That sounds almost impossible. For the moment, though, let's not pass judgment. We're still just doing math. There are going to be lots of us. We're going to be big. But lots of us in relation to what? Big in relation to what? It could be that compared with the world we inhabit, we're still scarce and small. Or not. So now we need to consider a third question: How big is the earth?
ANY state wildlife biologist can tell you how many deer a given area can support -- how much browse there is for the deer to eat before they begin to suppress the reproduction of trees, before they begin to starve in the winter. He can calculate how many wolves a given area can support too, in part by counting the number of deer. And so on, up and down the food chain. It's not an exact science, but it comes pretty close -- at least compared with figuring out the carrying capacity of the earth for human beings, which is an art so dark that anyone with any sense stays away from it.
Consider the difficulties. Human beings, unlike deer, can eat almost anything and live at almost any level they choose. Hunter-gatherers used 2,500 calories of energy a day, whereas modern Americans use seventy-five times that. Human beings, unlike deer, can import what they need from thousands of miles away. And human beings, unlike deer, can figure out new ways to do old things. If, like deer, we needed to browse on conifers to survive, we could crossbreed lush new strains, chop down competing trees, irrigate forests, spray a thousand chemicals, freeze or dry the tender buds at the peak of harvest, genetically engineer new strains -- and advertise the merits of maple buds until everyone was ready to switch. The variables are so great that professional demographers rarely even bother trying to figure out carrying capacity. The demographer Joel Cohen, in his potent book How Many People Can the Earth Support? (1995), reports that at two recent meetings of the Population Association of America exactly none of the more than 200 symposia dealt with carrying capacity.
But the difficulty hasn't stopped other thinkers. This is, after all, as big a question as the world offers. Plato, Euripides, and Polybius all worried that we would run out of food if the population kept growing; for centuries a steady stream of economists, environmentalists, and zealots and cranks of all sorts have made it their business to issue estimates either dire or benign. The most famous, of course, came from the Reverend Thomas Malthus. Writing in 1798, he proposed that the growth of population, being "geometric," would soon outstrip the supply of food. Though he changed his mind and rewrote his famous essay, it's the original version that people have remembered -- and lambasted -- ever since. Few other writers have found critics in as many corners. Not only have conservatives made Malthus's name a byword for ludicrous alarmism, but Karl Marx called his essay "a libel on the human race," Friedrich Engels believed that "we are forever secure from the fear of overpopulation," and even Mao Zedong attacked Malthus by name, adding, "Of all things in the world people are the most precious."
Each new generation of Malthusians has made new predictions that the end was near, and has been proved wrong. The late 1960s saw an upsurge of Malthusian panic. In 1967 William and Paul Paddock published a book called Famine -- 1975!, which contained a triage list: "Egypt: Can't-be-saved.... Tunisia: Should Receive Food.... India: Can't-be-saved." Almost simultaneously Paul Ehrlich wrote, in his best-selling The Population Bomb (1968), "The battle to feed all of humanity is over. In the 1970s, the world will undergo famines -- hundreds of millions of people will starve to death." It all seemed so certain, so firmly in keeping with a world soon to be darkened by the first oil crisis.
But that's not how it worked out. India fed herself. The United States still ships surplus grain around the world. As the astute Harvard social scientist Amartya Sen points out, "Not only is food generally much cheaper to buy today, in constant dollars, than it was in Malthus's time, but it also has become cheaper during recent decades." So far, in other words, the world has more or less supported us. Too many people starve (60 percent of children in South Asia are stunted by malnutrition), but both the total number and the percentage have dropped in recent decades, thanks mainly to the successes of the Green Revolution. Food production has tripled since the Second World War, outpacing even population growth. We may be giants, but we are clever giants.
So Malthus was wrong. Over and over again he was wrong. No other prophet has ever been proved wrong so many times. At the moment, his stock is especially low. One group of technological optimists now believes that people will continue to improve their standard of living precisely because they increase their numbers. This group's intellectual fountainhead is a brilliant Danish economist named Ester Boserup -- a sort of anti-Malthus, who in 1965 argued that the gloomy cleric had it backward. The more people, Boserup said, the more progress. Take agriculture as an example: the first farmers, she pointed out, were slash-and-burn cultivators, who might farm a plot for a year or two and then move on, not returning for maybe two decades. As the population grew, however, they had to return more frequently to the same plot. That meant problems: compacted, depleted, weedy soils. But those new problems meant new solutions: hoes, manure, compost, crop rotation, irrigation. Even in this century, Boserup said, necessity-induced invention has meant that "intensive systems of agriculture replaced extensive systems," accelerating the rate of food production.
Boserup's closely argued examples have inspired a less cautious group of popularizers, who point out that standards of living have risen all over the world even as population has grown. The most important benefit, in fact, that population growth bestows on an economy is to increase the stock of useful knowledge, insisted Julian Simon, the best known of the so-called cornucopians, who died earlier this year. We might run out of copper, but who cares? The mere fact of shortage will lead someone to invent a substitute. "The main fuel to speed our progress is our stock of knowledge, and the brake is our lack of imagination," Simon wrote. "The ultimate resource is people -- skilled, spirited, and hopeful people who will exert their wills and imaginations for their own benefit, and so, inevitably, for the benefit of us all."
Simon and his ilk owe their success to this: they have been right so far. The world has behaved as they predicted. India hasn't starved. Food is cheap. But Malthus never goes away. The idea that we might grow too big can be disproved only for the moment -- never for good. We might always be on the threshold of a special time, when the mechanisms described by Boserup and Simon stop working. It is true that Malthus was wrong when the population doubled from 750 million to 1.5 billion. It is true that Malthus was wrong when the population doubled from 1.5 billion to three billion. It is true that Malthus was wrong when the population doubled from three billion to six billion. Will Malthus still be wrong fifty years from now?
Looking at Limits
THE case that the next doubling, the one we're now experiencing, might be the difficult one can begin as readily with the Stanford biologist Peter Vitousek as with anyone else. In 1986 Vitousek decided to calculate how much of the earth's "primary productivity" went to support human beings. He added together the grain we ate, the corn we fed our cows, and the forests we cut for timber and paper; he added the losses in food as we overgrazed grassland and turned it into desert. And when he was finished adding, the number he came up with was 38.8 percent. We use 38.8 percent of everything the world's plants don't need to keep themselves alive; directly or indirectly, we consume 38.8 percent of what it is possible to eat. "That's a relatively large number," Vitousek says. "It should give pause to people who think we are far from any limits." Though he never drops the measured tone of an academic, Vitousek speaks with considerable emphasis: "There's a sense among some economists that we're so far from any biophysical limits. I think that's not supported by the evidence."
For another antidote to the good cheer of someone like Julian Simon, sit down with the Cornell biologist David Pimentel. He believes that we're in big trouble. Odd facts stud his conversation -- for example, a nice head of iceberg lettuce is 95 percent water and contains just fifty calories of energy, but it takes 400 calories of energy to grow that head of lettuce in California's Central Valley, and another 1,800 to ship it east. ("There's practically no nutrition in the damn stuff anyway," Pimentel says. "Cabbage is a lot better, and we can grow it in upstate New York.") Pimentel has devoted the past three decades to tracking the planet's capacity, and he believes that we're already too crowded -- that the earth can support only two billion people over the long run at a middle-class standard of living, and that trying to support more is doing great damage. He has spent considerable time studying soil erosion, for instance. Every raindrop that hits exposed ground is like a small explosion, launching soil particles into the air. On a slope, more than half of the soil contained in those splashes is carried downhill. If crop residue -- cornstalks, say -- is left in the field after harvest, it helps to shield the soil: the raindrop doesn't hit as hard. But in the developing world, where firewood is scarce, peasants burn those cornstalks for cooking fuel. About 60 percent of crop residues in China and 90 percent in Bangladesh are removed and burned, Pimentel says. When planting season comes, dry soils simply blow away. "Our measuring stations pick up Chinese soil in the Hawaiian air when ploughing time comes,"he says. "Every year in Florida we pick up African soils in the wind when they start to plough."
The very things that made the Green Revolution so stunning -- that made the last doubling possible -- now cause trouble. Irrigation ditches, for instance, water 17 percent of all arable land and help to produce a third of all crops. But when flooded soils are baked by the sun, the water evaporates and the minerals in the irrigation water are deposited on the land. A hectare (2.47 acres) can accumulate two to five tons of salt annually, and eventually plants won't grow there. Maybe 10 percent of all irrigated land is affected.
Or think about fresh water for human use. Plenty of rain falls on the earth's surface, but most of it evaporates or roars down to the ocean in spring floods. According to Sandra Postel, the director of the Global Water Policy Project, we're left with about 12,500 cubic kilometers of accessible runoff, which would be enough for current demand except that it's not very well distributed around the globe. And we're not exactly conservationists -- we use nearly seven times as much water as we used in 1900. Already 20 percent of the world's population lacks access to potable water, and fights over water divide many regions. Already the Colorado River usually dries out in the desert before it reaches the Sea of Cortez, making what the mid-century conservationist Aldo Leopold called a "milk and honey wilderness" into some of the nastiest country in North America. Already the Yellow River can run dry for as much as a third of the year. Already only two percent of the Nile's freshwater flow makes it to the ocean. And we need more water all the time. Producing a ton of grain consumes a thousand tons of water -- that's how much the wheat plant breathes out as it grows. "We estimated that biotechnology might cut the amount of water a plant uses by ten percent," Pimentel says. "But plant physiologists tell us that's optimistic -- they remind us that water's a pretty important part of photosynthesis. Maybe we can get five percent."
What these scientists are saying is simple: human ingenuity can turn sand into silicon chips, allowing the creation of millions of home pages on the utterly fascinating World Wide Web, but human ingenuity cannot forever turn dry sand into soil that will grow food. And there are signs that these skeptics are right -- that we are approaching certain physical limits.
I said earlier that food production grew even faster than population after the Second World War. Year after year the yield of wheat and corn and rice rocketed up about three percent annually. It's a favorite statistic of the eternal optimists. In Julian Simon's book The Ultimate Resource (1981) charts show just how fast the growth was, and how it continually cut the cost of food. Simon wrote, "The obvious implication of this historical trend toward cheaper food -- a trend that probably extends back to the beginning of agriculture -- is that real prices for food will continue to drop.... It is a fact that portends more drops in price and even less scarcity in the future."
A few years after Simon's book was published, however, the data curve began to change. That rocketing growth in grain production ceased; now the gains were coming in tiny increments, too small to keep pace with population growth. The world reaped its largest harvest of grain per capita in 1984; since then the amount of corn and wheat and rice per person has fallen by six percent. Grain stockpiles have shrunk to less than two months' supply.
No one knows quite why. The collapse of the Soviet Union contributed to the trend -- cooperative farms suddenly found the fertilizer supply shut off and spare parts for the tractor hard to come by. But there were other causes, too, all around the world -- the salinization of irrigated fields, the erosion of topsoil, the conversion of prime farmland into residential areas, and all the other things that environmentalists had been warning about for years. It's possible that we'll still turn production around and start it rocketing again. Charles C. Mann, writing in Science, quotes experts who believe that in the future a "gigantic, multi-year, multi-billion-dollar scientific effort, a kind of agricultural 'person-on-the-moon project,'" might do the trick. The next great hope of the optimists is genetic engineering, and scientists have indeed managed to induce resistance to pests and disease in some plants. To get more yield, though, a cornstalk must be made to put out another ear, and conventional breeding may have exhausted the possibilities. There's a sense that we're running into walls.
We won't start producing less food. Wheat is not like oil, whose flow from the spigot will simply slow to a trickle one day. But we may be getting to the point where gains will be small and hard to come by. The spectacular increases may be behind us. One researcher told Mann, "Producing higher yields will no longer be like unveiling a new model of a car. We won't be pulling off the sheet and there it is, a two-fold yield increase." Instead the process will be "incremental, torturous, and slow." And there are five billion more of us to come.
So far we're still fed; gas is cheap at the pump; the supermarket grows ever larger. We've been warned again and again about approaching limits, and we've never quite reached them. So maybe -- how tempting to believe it! -- they don't really exist. For every Paul Ehrlich there's a man like Lawrence Summers, the former World Bank chief economist and current deputy secretary of the Treasury, who writes, "There are no ... limits to carrying capacity of the Earth that are likely to bind at any time in the foreseeable future." And we are talking about the future -- nothing can be proved.
But we can calculate risks, figure the odds that each side may be right. Joel Cohen made the most thorough attempt to do so in How Many People Can the Earth Support? Cohen collected and examined every estimate of carrying capacity made in recent decades, from that of a Harvard oceanographer who thought in 1976 that we might have food enough for 40 billion people to that of a Brown University researcher who calculated in 1991 that we might be able to sustain 5.9 billion (our present population), but only if we were principally vegetarians. One study proposed that if photosynthesis was the limiting factor, the earth might support a trillion people; an Australian economist proved, in calculations a decade apart, that we could manage populations of 28 billion and 157 billion. None of the studies is wise enough to examine every variable, to reach by itself the "right" number. When Cohen compared the dozens of studies, however, he uncovered something pretty interesting: the median low value for the planet's carrying capacity was 7.7 billion people, and the median high value was 12 billion. That, of course, is just the range that the UN predicts we will inhabit by the middle of the next century. Cohen wrote,The human population of the Earth now travels in the zone where a substantial fraction of scholars have estimated upper limits on human population size.... The possibility must be considered seriously that the number of people on the Earth has reached, or will reach within half a century, the maximum number the Earth can support in modes of life that we and our children and their children will choose to want.

CHICAGO (AP) -- Researchers have found that every hour preschoolers watch television each day boosts their chances -- by about 10 percent -- of developing attention deficit problems later in life.
The findings back up previous research showing that television can shorten attention spans and support American Academy of Pediatrics recommendations that youngsters under age 2 not watch television.
"The truth is there are lots of reasons for children not to watch television. Other studies have shown it to be associated with obesity and aggressiveness" too, said lead author Dr. Dimitri Christakis, a researcher at Children's Hospital and Regional Medical Center in Seattle.
The study, appearing in the April issue of Pediatrics, focused on two groups of children -- aged 1 and 3 -- and suggested that TV might overstimulate and permanently "rewire" the developing brain.
