The American Southwest has horribly mismanaged it's fresh water supply. Tulare Lake, Hoover Dam, and Las Vegas are just some examples of the American Southwest's horrible fresh water management. My suggestion is does the rest of the United States and North America have a right to the fresh water contained in the Great Lakes? Would a pipeline from Chicago to Los Angeles or Mexico City be better for the environment than a desalination plant?
Don't need to fuck up one ecosystem just to help one thats already beyond repair, just do a reverse dust bowl and send the calis to oklahoma.
