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.
