Once water is ruined, it's gone. Either via fracking, or by our our insatiable demand for bottled water (it takes more water to make a plastic bottle than is contained in it). Lovely Sylvia Earle quote, tireless energy for our blue planet!
Save water by washing fruits and vegetables in a pot of water instead of letting the water run while cleaning them. And then you can also reuse the water for watering your plants instead of wasting it.
