Killing cute animals is probably the only way to convince people that growing marijuana is bad, actually.
Enormously unjust rates of incarceration aside, one of the biggest arguments cited in favor of marijuana legalization in this country is that it's safe to use and doesn't have many long-term side effects. Tell that to the fishers that live in the southern Sierra Nevada area, though. According to scientists from U.S. Forest Service's Pacific Southwest Research Station, UC Davis, UC Berkeley, and Integral Ecology Research Center, they're dying out because of the rat poison that local marijuana growers use to protect their crops. Happy now, potheads?
