I don't know if you remember a couple years ago when they were finding barrels of bodies, guns, and other fun things in Lake Mead (near Vegas)? That was drying up because the river that feeds it has been getting diverted for farm use (and probably Nestlé, too). It's a huge problem in California, as well. Whole ecosystems are disappearing due to damming and diverting of rivers and streams. It's not at all sustainable
