Your peers and experience have left you woefully misinformed about cotton, and all the products that come from cotton. I grew up on a farm, had my secondary education conducted in the school of agriculture, and have worked with meat suppliers for over two decades. In all that time, I've never once heard of cotton byproducts causing beef cattle to go blind. Have you contacted Alex Jones?
Most farmers I know have a much better grasp of science than you do. But then, they don't believe everything they hear or read either.
Some farmers have Ph.D.s and do research. I come from an agricultural background, too, and have a Ph.D.
One of the most popular talks I ever saw at a scientific conference was presented by a farmer, complete in plaid shirt, jeans, cowboy boots and big hat. The good doctor/farmer spoke about cows pooping dioxin contaminated poop. (They were chewing on the pasture fencing, and a chemical used in treating the wood was converted to dioxin in their guts.)
That talk was standing-room only. The incongruity of a farmer addressing a bunch of stuffy scientists will always be stuck in my mind.
