 The thing has changed the way the earth is rotating. We're pumping too much groundwater because so much of government policy pays farmers to do that. There are some tribes where there's an effort to protect certain places, certain waterways, because it is a sacred place to them. I think at the end of the day there is no perfect city that's doing everything right, but there are little examples or experiments in cities. We also have to think not how do we build to the capacity of today, but how do we manage our life out of water in the year 2050 or beyond.
