I saw an ad for being vegan saying either don’t flush your toilet for 6 months, don’t shower for 3 months or don’t eat a burger once. But isn’t all of our water basically renewable and no matter if we do any of these things, it just goes back into the water cycle and we’ll reuse it eventually, even if we have to clean it somehow? What’s the big deal?
In: Earth Science
Water can be renewed, but that requires energy. Water treatment plants use a lot of energy to make sewage into drinkable water again.
Nature can do some of the work, but it does so more slowly than we need, and because of that we are fouling more and more of nature and making it less effective at the water cycle every day.
So the big deal is that we either need to spend much more money to purify water, we need to use less water, or we need to be prepared to die as a civilization because we refuse to do either of those two. And of course, that also applies to a lot of other environmental concerns as well.
