Cotton is literally the most toxic crop on the planet. While only 3% of the world's farm acreage is cotton, these crops are sprayed with up to 25% of the world's pesticides and herbicides, including some of the most toxic ones, such as aldicarb. Few people realize that 60% of a cotton crop, by weight, enters the food chain in the form of cottonseed oil which is used widely in processed foods, and a cottonseed feed for cows, ending up in meat and dairy products. Cotton is comprised of fiber and seed: 40% fiber to 60% seed by weight.
