Agriculture is 80 percent of water use in California, I think it is likely the same in AZ and UT.
iMO it is not really so much about housing/industrial growth etc… but more about how we are going to grow food and what we eat in the future, housing growth is really a non-issue but it makes great headlines LOL.
I really don’t want to get into the whole climate change debate. but it is largely the same, it is popular to blame it on cars/suburbia etc.. but in reality cargo ships and Agriculture emit far more. If you to want to realty help, stop buying so much crap from Costco LOL.
It is almost pointless IMO, for every ton of greenhouse gas the USA removes, China, Africa and India probably add about three.
