If we are serious about water conservation we would quickly shift away from animal agriculture and transition to a mostly plant-based food system.  Unfortunately, I fear most people would rather destroy the planet than give up their hamburgers and bacon.

Animal agriculture not only a spectacularly irresponsible misuse of our most precious resource, it also produces more climate-change causing green-house gases than the entire transportation industry.  If we want to destroy the planet as quickly as possible producing lots of meat and dairy is a pretty good way to do it.
