The ecological, economic and agronomic disaster accompanying herbicide-tolerant transgenic crops is by now well known: over 10 million acres of superweeds resistant to Monsanto’s weedkiller, RoundUp; farm machinery breaking on RoundUp-resistant pigweed thick as a baseball bat; Monsanto paying farmers to spray their fields with competitors’ herbicides; a new generation of transgenic crops in the pipeline engineered to withstand older even more dangerous chemicals like 2,4-D.

Last week brought more bad news for Monsanto: the same phenomenon is also occurring in insect pest populations that are developing resistance to transgenic “Bt corn” in the Midwest.

Like many people, I once believed in the safety of RoundUp. Back in the 1980s when I was a young graduate student in ecology, it was the “safe” herbicide of choice for clearing weeds from study plots.

Monsanto would like us to continue to believe their flagship product is safe, but the data are increasingly saying otherwise. The latest? Widespread exposure is a near certainty, since RoundUp — now linked to birth defects — shows up regularly in our water and air.

Twelve years passed. And without prior notice, federal and state pesticide regulators announced a surprise settlement last month, acknowledging that, compared to their white peers, Latino schoolchildren had been disproportionately impacted by use of pesticide fumigants. While the case marks a step towards recognizing environmental injustice, it fell short of providing compensation for children, many of whom have since graduated from high school, or of protecting future generations from pesticide drift.

Men who live in neighborhoods that experience pesticide drift are 1.5 times more likely to develop prostate cancer.

This is what scientists found in a one-of-a-kind study that compares rates of the cancer among men who lived near agricultural fields where methyl bromide, captan or organochlorine insecticides were applied with those who lived farther from drifting pesticides.

Yesterday, PAN joined United Farm Workers (UFW) for part of their 13-day, 200-mile pilgrimage to Sacramento, demanding fair policies for farmworkers.

About 20 people affliliated with PAN, including Co-Director Kathryn Gilje, joined the march for workers' rights yesterday morning on a stretch of highway between Lodi and Galt. "Peak fumigation season in California's strawberry fields is just a few weeks away," she said. "Governor Brown should follow the science, ensure fair treatment for farmworkers and take immediate steps to pull methyl iodide off the shelves."
