There's been a recent backlash against the vilification of insecticides, mainly focused on the apparent wonderfulness of DDT, so wrongly demonized in Rachel Carson's Silent Spring. Well, break back out the devil horns, because a new study reports that those with a sustained, low-level exposure to pesticides are 70 percent more likely to develop Parkinson's Disease. To some degree, we're talking gardening here, but the real issue is occupational exposure: ranching, fishing, farming, etc. In a depressing turn, these are coordination-intensive occupations, and early onset Parkinson's deprives their participants of their livelihood.
Maybe the organic boosters have a point.
