You're joking, right???
What do you think manure is??? It's sold in stores all over the country as "potting soil". Farmers have been putting poop on the soil as fertilizer since before the Egyptians were the dominant civilization on earth. All "organic" or "naturally grown" foodstuffs were fertilized with manure. Think about that when you pick up an organic bunch of carrots next time.
Creating rules and regulations without proper knowledge leads to stupid rules and tyranny. The regulation to use eco-friendly materials on the space shuttle external fuel tank lead to the destruction of the Columbia. The non-eco-friendly materials that were used were tougher than the "new" and "improved" materials. The across the board banning of DDT worldwide has caused the deaths of millions from insect borne diseases. Don't make knee-jerk reactions.
Thanks for that! I used to tell people my garden (which was one of the best if not the best in my small town of 750), that everything eaten from it was grown in pure manure. Of course it was composted cow manure but have you seen fresh cow manure? I could eat from the bounty of my composted manure but seeing a dog of ours slurp up some fresh cow manure sent me into a fit of gagging that would not quit!
