I know we need to conserve water and such but why? Doesn’t it eventually flow back into the ground or evaporated and rained back down regardless of how it’s consumed, so it’s a cycle? Do we lose a bit per cycle?

If you look at the surfaces around you, a lot of them are covered in concrete, or the topsoil is scraped flat to lay foundations for housing, etc. Areas of farmland are tilled and repeatedly have plants growing/pulled up, which takes nutrients away and loosens the structure even more/leaves it vulnerable to being washed away in rain. Compare that to a forest where large root and mycelium (fungal) structures are maintained over the years, holding the soil in place like a sponge and building it as more leaves fall/plants die and their roots rot. We are projected to run out of usable top soil by 2050-its one of the more unsexy issues we are facing as a society. Topsoil holds tons of water and it keeps it in place and keeps underground reservoirs level. If we fuck up the top soil, we fuck up the reservoirs! So that’s why ecological farming practices (no dog, permaculture, etc) are so important, and why /r/nolawn is the shit.
Edit: this is just one piece of the puzzle, many factors contribute.
