It took years for scientists to fully understand the danger of Agent Orange, but that hasn't stopped Dow Chemical from bringing the specter of Agent Orange to our food supply.
Dow Chemical has genetically engineered pesticide-promoting varieties of corn and soybeans to survive repeated dousing with 2,4-D. The herbicide 2,4-D is considered to be the less toxic half of Agent Orange. But it's also the seventh largest source of dioxins in the environment. According to the World Health Organization, dioxins are highly toxic persistent environmental pollutants that "can cause reproductive and developmental problems, damage the immune system, interfere with hormones and cause cancer."
