On a recent front page of The Salt Lake Tribune, a frightening, oversized headline read, "Highest rate in the nation, 1 in 32 Utah boys has autism." Less well publicized, another national story ran the same day: "New pesticides linked to bee population collapse." If you eat food and hope to do so a few years from now, this should be equally frightening. A common denominator may underlie both stories.
The nervous system of insects is the intended target of these insecticides. They disrupt the bees homing behavior and their ability to return to the hive, kind of like "bee autism." But insects are different than humans, right? Human and insect nerve cells share the same basic biologic infrastructure. Chemicals that interrupt electrical impulses in insect nerves will do the same to humans.
But humans are much bigger than insects and the doses to humans are miniscule, right? During critical first trimester development, a human is no bigger than an insect, so there is every reason to believe that pesticides could wreak havoc with the developing brain of a human embryo. But human embryos aren't out in corn fields being sprayed with insecticides and herbicides, are they? A recent study showed that every human tested had the world's most popular pesticide, Roundup, detectable in their urine at concentrations between five and twenty times the level considered safe for drinking water.
