We have even in the United States seri­ous and grow­ing water scarci­ty chal­lenges. We have con­t­a­m­i­na­tion prob­lems with chem­i­cals that we have not ade­quate­ly reg­u­lat­ed here in the United States. We have con­flicts between states in the United States about who gets to use what water to do what. We have evi­dence that cli­mate change is already influ­enc­ing water demand, affect­ing water avail­abil­i­ty, chang­ing extreme events. There are a whole suite of water-related prob­lems, here, unre­lat­ed to these basic human need chal­lenges that’re press­ing in oth­er parts of the world.
