In relation to your hill: While you’re entirely correct, that’s absurdly small potatoes compared to industrial water use. Yes, we should be conscious of our water use and limit unnecessary overuse, but a higher priority ought to be regulating industrial use. Data centers are the obvious example of using way too much for bullshit that ain’t worth the water or power. Speaking of power, we could reduce water use by power plants. Nearly all generate power by boiling water. I’m a power plant operator at a plant that happens to use reclaim water as our source water, and we purify on-site for the main process, and we have a brine concentrator and crystallizer on-site to recycle the cooling tower blowdown and remove the solids to a dumpster that goes to a landfill. Unfortunately we burn methane, so I can’t say that we’re green, but we at least discharge zero water into local waterways (except storm drains when it rains).

My hill: Vote with your wallet. If you really believe in something, stop giving money to companies fighting against it. I won’t buy chikfila because the owners actively spend money on gay conversion camps and lobby to reverse the legality of same sex marriage. It’s impossible to research every little thing before every purchase, and sometimes there’s no reasonable alternative, but something like chikfila is easy to avoid. There is no ethical consumption under capitalism, but don’t let perfect be the enemy of good. Little changes can add up, and doing anything even a little bit better is an improvement over not trying.

Bonus hill: Put your fucking grocery cart into the cart corral. It takes ten seconds and prevents cars from getting hit. It’s kind of the simplest measure for societal decency. I don’t believe in the death penalty, but what value are you contributing to society if you’re too selfish to return your fucking cart?
