Mexican criminal organizations use national parks for pot cultivation

Ok one more thing from the report that should hopefully piss off pot smokers.

Marijuana cultivation on public lands has created a litany of problems. An increasing number of unsuspecting
campers, fishermen, hikers, hunters, and forest and park officials have been intimidated, threatened, or even physically harmed when they neared marijuana cultivation
sites. To establish and maintain a marijuana field, traffickers must clear cut native plants and trees; poach and hunt wildlife; devastate the soil with insecticides, herbicides, pesticides, and fertilizers; and divert natural waterways like springs, streams, and creeks. According to the National Park Service, 10 acres of forest are damaged for every acre planted with marijuana, with an estimated cost of $11,000 per acre to repair and restore land that has been contaminated with the toxic chemicals, fertilizers,
irrigation tubing, and pipes associated with marijuana cultivation.

By smoking pot, you might think that you are being one with the land, but I'm doing more to help the environment (not that I really give a crap one way or another) by not smoking pot than you are by lighting your doobie.
