Hot showers are not the problem. Unless you live in the Sahara, you probably have plenty of water. At least we do here and that's all that counts. If you don't there, ah well. The real problem is breathing. You inhale good oxygen, then your unpure and imperfect body converts it to carbon dioxide (gasp!) and you become like a car, spewing your green house gas all over the place and heating up the planet. And then there is human farting, which is far worse than cow farting simply because there are way too many humans spewing daily doses of metahne out their south end.
The solution to all these problems is simple. 1. Do like the French and limit yourself to one shower per week of about 5 minutes max. If you wear a surgical mask at all times you will not notice the fragrances around you. 2. Don't fart. Put a cork in it. If you contain it internally, it will be absorbed into the lining of your intestines and not escape into the air until you burst, at which point you will care less. 3. Stop breathing.
