The most obvious ways to help the environment are often small actions that, when taken by many people, can make a difference.

Enter number one in the shower! If you pee in the shower, you can avoid flushing the toilet. The water you’re already running in the shower will wash away your urine. If you shower once per day, that’s one less flush, which saves between 1.3 and 3.5 gallons of water per person per day!

Most toilet tissue is made from virgin wood pulp. That means we’re literally flushing forests down our drains every day. Combining pee time with shower time can also put a dent in your toilet paper consumption!

Finally, for those of you who are concerned about how clean your urine actually is, we have some good news. Pee contains a very low amount of bacteria—less, in fact, than what’s normally lingering on your skin—and it’s healthy bacteria.(Plus, there’s a near 100 percent chance you’re washing your hands afterward since soaping up is pretty much the reason you’re showering in the first place.)
