You can grow almonds elsewhere, they are not needed for daily life
CA, apparently, grows almonds for the entire United States, and 80% of the world's almonds, too.
Sure, I'm not saying they don't, but it isn't a critical crop for day to day life, biologically speaking. No one is going to die for not eating almonds.
Is it economically important? For sure.
Is it critical for living? No.
