Gawd, this is extremely unpopular to say in some circles especially in California (looking at you Boomers of Sierra Club), but a West Coast Manhattan project on how to sustainably desalinate Ocean Water would make most of these “lipstick on a pig” solutions moot.
“Don’t use too much water in the dishwasher, don’t grow almonds, don’t build too many apartments, we don’t have the water”
Getting screamed at with all this while living next to a literal Ocean of water is just so tiringly frustrating.
