I don’t know about anyone else, but I have always been confused as to how wasting water contributes to your carbon footprint. I used water respectfully because it is expensive, but I finally found out how it affects the amount of carbon put into the environment! It takes a lot of energy to run a water plant, distilling and purifying and pumping water all the time. The energy that runs these factories is what emits carbon.
Also, a small tip on how to conserve water- turn off the water while you shave, especially if your shower isn’t made to conserve water.
