Can we stop labeling everything evil? It works or it doesn't. If almonds are fundamentally unsustainable at scale, fine. Say that. This is not a children's fairy tale with an evil ogre and a fair prince. Let's stop casting everything as good v. evil. Works or doesn't work is sufficient.
Whatever the ultimate effects are, I highly doubt that almond farmers are sinister, malevolent beings who want to destroy humanity. If there's a better way they can do what they do, I'm sure they'll be happy to do it.
