A lot of things shouldn't be grown where they are. But if we write off the ones currently there, then we lose that crop for years to come. Almonds aren't like lettuce you can restart in a few weeks. They take about 5 years to start producing, and longer to a full crop. California produces 80% of the world's almonds and 100% of the United States’ commercial supply. Lose those trees, and effectively lose commercial almond production globally for at least 5 years. That is not a good thing at all. And it's not the only crop where that's true.
California alone produces 25% of America's food and 40% of its fruits, vegetables, and nuts. If we lose the West Coast food production, the rest of America goes hungry about 3 days later and many other countries take a bad hit also. We can in theory raise many foods elsewhere -- most of the same vegetables will grow in the South or Midwest -- but farmers there aren't equipped for that. T-America managed a big shift quickly, but they were both lucky in timing and much better prepared. We couldn't do that here even with the same timing.
If this distresses you, the best thing individuals can do to fight it is eat local. The more we do that, the higher the demand for farmers to diversify, so that more produce is grown locally instead of shipped from California. That will slightly reduce the damage and greatly improve the recovery, because it's much easier to expand an established farm than to start from scratch.
