Daily Mail:  “In California, illegal marijuana farms are taking over thousands of acres of land as toxic wastes are increasingly corrupting ecosystems. California is responsible for the majority of illegal U.S. marijuana farming. New data says the state holds ‘731,000 pounds of solid fertilizer, 491,000 ounces of concentrated liquid fertilizer and 200,000 ounces of toxic pesticides.’ The United States Environmental Protection Agency announced in 2011 its planned to ban toxic fertilizers like zinc phosphide.
