Not as much as you think. Droughts in there happen regularly, climate change contributed less than 25% to the last one.
It's a combination of normal weather cycles and other things.
And then they have over 80% of world's almond production. That's just mental considering they already have water issues. That isn't sustainable. Like it wouldn't be sustainable to have 80% of cattle in one place.
People should be looking at the whole picture. Carbon footprint, local effects etc.
Anything can be bad if it's too much of it.
