It's the guilty pleasure most of us have committed. We’re talking about peeing in the shower and according to the numbers, you shouldn't feel guilty at all.
An article on IFL Science makes a very sound mathematical argument that we all should let it flow behind the shower curtain. It's based on the fact that every time you pee you have to flush the toilet.
So if the average flush uses 6 liters of water and the average adult pees 7 times a day, that means that each adult uses up 42 liters, or just over 11 gallons, of water peeing a day.
With 319 million people in the U.S., can you figure out how much water is flushed away in a year? If you don’t have time to crunch the numbers, we’ll just tell you -- over a trillion gallons.
If everyone peed in the shower at least once a day, over 180 billion gallons of water would be saved.
So the next time you have the urge to pee in the shower, don't feel guilty, feel proud -- you're saving the earth one call of nature at a time.
