But, of course, the reason it was so top heavy and so complex to start with was because so many of the issues that concerned people about the environment and human health were not well understood by the activists and those who shouted the loudest at the time. In fact, there were a number of books written about the GE corn that was going to infect all the other corn and cause all kinds of problems with crops. That never happened. The other problem that this legislation was intended to address, of course, was the legacy of toxic chemicals produced in those decades after World War II, which included DDT, pentachlorophenol, 2,4,5-Trichlorophenoxyacetic Acid, Lindane, and Chlordane. They might have been used to treat timber or even to treat food, and, of course, what we know is that they were toxic to humans, toxic to future generations, as well as to plants and animals. Now, all of those chemicals have been banned and removed from use as far as practical, and, of course, there are much better controls now on how they're used.
