It's not so much that almonds aren't water intense, as that things like beef and dairy (which are also heavily produced in California) are so much worse: https://www.truthordrought.com/almond-milk-myths

Yet we never see beef or dairy demonized the way almonds are.

Believe me, there are better plant milks than almond milk (pretty much any of them), but dairy has such a higher impact on the environment (as does beef), it's incredibly disingenuous and hypocritical to complain about almonds before addressing dairy and beef.
