Via Yahoo News: "...several California wildlife researchers reported that pot farms are wreaking havoc on wildlife ranging from endangered salmon to black bears..." "...grow ops near just one small tributary of the Eel River were siphoning up to 18 million gallons of water from the river’s watershed. That water is crucial for species like the endangered Coho salmon as well as Chinook Salmon and steelhead, all of which swim up the Eel tributaries to spawn."
