Considerably more water is used to raise cattle than plants. And then the plants that they feed on also need water.
People's preferences haven't changed. Beef continues to be very popular, as do public fountains. The choice not to consume meat (at least here) is mostly associated with pretentious, upperclass people who like yoga and are keenly interested in social justice (there is even a word for this type of person: fresas, which literally means strawberries but here means, well, that type of person).
Eating or not eating meat is more about adopting cultural, class, and identity signifiers than any real correlation with the local water situation.
Peoples' preference for war hasn't changed either (most people don't want it), but we still find ourselves in conflict at every turn. That's because you can't go too long without confronting the objective physical reality of scarcity of resources.
No, more like life style participation.
>I guess, in that case, the "unpretentious, lower class people who hate yoga" would have those tree huggers to thank.
We need many countries to make national-level policies about this. The Instagram people are a smug drop in the bucket.

That correlation seems made up. Has there been an increase of scarcity-driven wars? Most wartorn places don't seem to be resource scarce.
