This is why all the hand-wringing about "take shorter showers!!!" is so braindead. The issue is agriculture, full stop. Of course, we all need food to eat, but as you point out we could produce just as much food if we just modernized our irrigation practices. I'm not saying that would be cheap, or that we shouldn't have government support for that modernization, but whenever I hear some nonsense about how we should stop washing our cars I just tune that out. It's a form of green washing when we focus on inconsequential bits and then let the biggest water users continue to waste water.
