Cowshit, YES! When you think about it, isn't it funny that so many people these days want their tomatoes grown in cowshit? When I was a boy, I used to drive a John Deere with a manure spreader on the back, up and down the fields that belonged to my cow milker boss. That spreader would throw the stuff everywhere, and I got a kick out of telling people that I threw cowshit for a living (kind of like a politician, come to think of it).
I can see the protesters with their signs: "Chemicals, NO! Cowshit, YES!"
