Cancer in the Air, Food, and Water

Lyndsey Layton writes in the Washington Post that:
An expert panel that advises the president on cancer said Thursday that Americans are facing “grievous harm” from chemicals in the air, food and water that have largely gone unregulated and ignored.
Somebody noticed!

The President’s Cancer Panel called for a new national strategy that focuses on such threats in the environment and workplaces.

Epidemiologists have long maintained that tobacco use, diet and other factors are responsible for most cancers, and that chemicals and pollutants cause only a small portion — perhaps 5 percent.

The presidential panel said that figure has been “grossly underestimated” but it did not provide a new estimate.

“With the growing body of evidence linking environmental exposures to cancer, the public is becoming increasingly aware of the unacceptable burden of cancer resulting from environmental and occupational exposures that could have been prevented through appropriate national action,” the panel wrote in a report released Thursday.

Federal chemical laws are weak, funding for research and enforcement is inadequate, and regulatory responsibilities are split among too many agencies, the panel found.

The problem is not too many agencies. Here’s the problem: Continue reading →

Candling Longleaf

In case you wondered why the growing bud on a longleaf pine is called a candle:

HFCS downfall?

Let’s hope Melanie Warner, writing in bnet, is right about The Death of High Fructose Corn Syrup:
The back-to-back, double whammy announcements that PepsiCo (PEP) is ditching high fructose corn syrup in Gatorade along with the results of a scathing new study from researchers at Princeton make it official — allies of the controversial sweetener have lost the war.

What the Princeton researchers found was A sweet problem: Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain, as we noted here a while back. And, as we noted last year, there’s also an eerie correlation of the spread of HFCS into the food supply with the rise of obesity in the U.S.

Here’s Melanie Warner again, this time in the New York Times:

Hunt’s ketchup is among the latest in a string of major-brand products that have replaced the vilified sweetener. Gatorade, several Kraft salad dressings, Wheat Thins, Ocean Spray cranberry juice, Pepsi Throwback, Mountain Dew Throwback and the baked goods at Starbucks, to name a few, are all now made with regular sugar.

Why is Big Food buckling about bogus sugar?

What started as a narrow movement by proponents of natural and organic foods has morphed into a swell of mainstream opposition, thanks in large part to tools of modern activism like Facebook, YouTube and Twitter and movies like “Food, Inc.” and “King Corn.”
Well, well. Voting at supermarket checkout seems to be working after all!

Hamster Roundup: sterility and infant mortality

Jeffrey Smith writes in Huffingtonpost about Genetically Modified Soy Linked to Sterility, Infant Mortality in Hamsters:
“This study was just routine,” said Russian biologist Alexey V. Surov, in what could end up as the understatement of this century. Surov and his colleagues set out to discover if Monsanto’s genetically modified (GM) soy, grown on 91% of US soybean fields, leads to problems in growth or reproduction. What he discovered may uproot a multi-billion dollar industry.

After feeding hamsters for two years over three generations, those on the GM diet, and especially the group on the maximum GM soy diet, showed devastating results. By the third generation, most GM soy-fed hamsters lost the ability to have babies. They also suffered slower growth, and a high mortality rate among the pups.

Not just a little higher: five times highher infant mortality.

And it’s not necessarily the soybeans themselves: Continue reading →

Beta Agonists and Bovine Growth Hormone

Martha Rosenberg writes in CounterPunch, If You Liked Bovine Growth Hormone, You’ll Love Beta Agonists:
As much as twenty percent of Paylean, given to pigs for their last 28 days, Optaflexx, given to cattle their last 28 to 42 days and Tomax, given to turkeys their last 7 to 14 days, remains in consumer meat says author and well known veterinarian Michael W. Fox.

Though banned in Europe, Taiwan and China–more than 1,700 people were “poisoned” from eating Paylean-fed pigs since 1998 says the Sichuan Pork Trade Chamber of Commerce– ractopamine is used in 45 percent of US pigs and 30 percent of ration-fed cattle says Elanco Animal Health which manufactures all three products.

What effects could these drugs have?

According to Temple Grandin, Professor of Animal Science at Colorado State University, the “indiscriminant use of Paylean (ractopamine) has contributed to an increase in downer non-ambulatory pigs,” and pigs that “are extremely difficult to move and drive.” In Holsteins, ractopamine is known for causing hoof problems, says Grandin and feedlot managers report the “outer shell of the hoof fell off” on a related beta agonist drug, zilpateral.

A article in the 2003 Journal of Animal Science confirms that “ractopamine does affect the behavior, heart rate and catecholamine profile of finishing pigs and making them more difficult to handle and potentially more susceptible to handling and transport stress.”

Surely such animal drugs would have no effects on human? Well, except they’re used to treat children for asthma. Not the sort of thing you really want in the food and water supply.

Rosenberg asks how did this happen, and points out the answer: massive lobbying by big agribusiness.

The FDA’s approval of a drug for food that requires impervious gloves and a mask just to handle is reminiscent of the bovine growth hormone debacle.

And in that debacle, Monsanto didn’t just lobby the FDA, it lobbied the press, including making Fox rewrite a story 80 times.

Divide and Diminish, or Preserve and Survive?

Eagle1 Olivia Judson writes about Divide and Diminish:
A different process goes on when an island forms by splintering. Here, the ecosystem is pre-existing: the island is created with a set of residents already in place. But it is now too small to support them all.

What happens next is a kind of unraveling, a fraying, a disassembling such that the ecosystem becomes simpler, so as to fit the space that is now available. On those recently-created islands of Indonesia, for example, the smallest islands are home to many fewer species than the largest islands. And, as you’d expect, you don’t find big animals on the smallest islands either.

When we humans burn tracts of forest, or make islands in some similar way, the immediate impacts depend on a suite of factors, including how many islands there are, how big they are, and how close they are together. It also matters what is between them. Fields may be more hospitable to wildlife than roads or water; under some circumstances, life forms may be able to flit from one fragment to another, and the “island” nature of the fragments will be reduced. Perhaps we can use such patterns to shape how we use land, to try and minimize the impact we have.

Perhaps.

She’s not talking about prescribed forest burns, which are actually necessary for longleaf pine forest ecology. She’s talking about burns that destroy forests.

The once-mighty longleaf pine ecology that spread from eastern Virginia to east Texas now only exists in tiny islands separated by cities, fields, and roads. Maybe we should preserve the few patches that are left. This isn’t just about plants and animals, you know, it’s also about flood control, food supply, and living conditions.

Half a century ago we overused pesticides, in particular DDT, which caused birds’ eggs to become too fragile. Bald eagles vanished from many places. But sometimes they come back, when we stop poisoning them and instead save some habitat.

The eagle pictured was just sitting beside the road as we drove by. There are more in nearby counties. Picture by Gretchen Quarterman, 23 March 2010.

Making Forests Pay While Benefiting Everybody

Spider against the pines The state of Georgia already finances a Conservation Reserve Program (CRP) to plant longleaf pines with associated native ground cover (partridge pea that the quail like, and bunch grasses such as wiregrass that help fuel periodic fires).

However, CRP payments typically only last 10 years and not more than 15 years, and such trees usually eventually get cut for sawtimber or pulpwood. Now that’s better than cotton: much less pollution involved and far more carbon sequestered.

But even better would be to treat such replanting as real reforestration and sell carbon sequestration rights for such forests. Like what is being planned in Florida: Continue reading →

Fat Rats on HFCS

Hilary Parker writes about research at Princeton:
“Some people have claimed that high-fructose corn syrup is no different than other sweeteners when it comes to weight gain and obesity, but our results make it clear that this just isn’t true, at least under the conditions of our tests,” said psychology professor Bart Hoebel, who specializes in the neuroscience of appetite, weight and sugar addiction. “When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they’re becoming obese — every single one, across the board. Even when rats are fed a high-fat diet, you don’t see this; they don’t all gain extra weight.”
Every single rat got fat on HFCS.

And the researchers are not talking about a little extra weight: Continue reading →
