There is a new thread on the healthy living forum about a book called The Hundred Year Lie. It deals with the quality of our food supply and the genetic findings of people, animals, fish, etc. that have become mutants over that time due to all the chemicals in our food and water.
I have not read the book, and have not researched the veracity of his findings yet.
