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 →

Mutant Pigweed vs. Glysophate-Resistant Corn, Soybeans, and Cotton

It’s a funny thing about monocultures. They’re highly vulnerable to anything that affects that particular variety. Dr. Mae-Wan Ho writes:
The scene is set at harvest time in Arkansas October 2009. Grim-faced farmers and scientists speak from fields infested with giant pigweed plants that can withstand as much glyphosate herbicide as you can afford to douse on them. One farmer spent US$0.5 million in three months trying to clear the monster weeds in vain; they stop combine harvesters and break hand tools. Already, an estimated one million acres of soybean and cotton crops in Arkansas have become infested.

The palmer amaranth or palmer pigweed is the most dreaded weed. It can grow 7-8 feet tall, withstand withering heat and prolonged droughts, produce thousands of seeds and has a root system that drains nutrients away from crops. If left unchecked, it would take over a field in a year.

Meanwhile in North Carolina Perquimans County, farmer and extension worker Paul Smith has just found the offending weed in his field [3], and he too, will have to hire a migrant crew to remove the weed by hand.

Here’s the good news: Continue reading →
