Ehhhhh clean fresh water is a problem everywhere. Plenty of environmentally conscious people are aware of it. Politicians and the common lay person in developed countries however don't give two shits. I had a whole class on global water sources. It's a definite concern.
That's why China invaded Tibet. Pretty sure all of Chinas major rivers have their headwaters in the Himalayas. As crazy as it sounds there were a bunch of people back in the 30's in the intermountain west that had devised schemes and plans for pipelines to carry water from Canada to California, Arizona, ect...and they even felt if Canada didn't play nice war would be justifiable.
At this point California needs to reassess how much AG contributes to the State Economy (2 % of GDP according to some sources) as a whole and whether that justifies the resources consumed. Would a healthy fishing industry based on restoring the hydrology of the San Joaquin and Sacramento River deltas that would then support a restored pacific salmon population provide more economic benefit and be more sustainable? The Ag economy in Cali has been and probably allways will be super one sided in terms of whom it benefits. It is dominated by large corporations for the most part who rely on super cheap, more often than not undocumented labor and or mechanization. So it's not a big time job creator as a whole. As to who consumes it's products a large percentage of the nuts produced in California are processed and shipped to China for consumption. It's also interesting to note that in California there is a strong correlation between the poverty level of areas and those areas reliance on AG as a major factor in their economies.
I think Texas and Florida are going to be looking at serious water issues in the very near future. Texas due to population growth exceeding its resource capacity in terms of water and Florida due to salt water intrusion into its ground water supply due to sea level rise associated with climate change.
Anyhow, if any of you all are interested in "the book" on western water use read Caddillac Desert by Marc Reisner
In summation A Camp should be able to keep his pool because it is less than a drop in a rather large bucket.
