Do you shave, brush your teeth, and/or do the dishes with the faucet running the whole time? Enjoy long hot showers? Do less than full loads of laundry with the dial set on “large” load? You might be a three-bathtubber …
On Wednesday, we blogged about a new study by The Nature Conservancy’s vanguard scientist (sweet job title!) Rob McDonald and Conservancy scientist Carmen Revenga. The paper, which was published by PNAS, took a look at the challenge of maintaining sustainable water supplies to accommodate growing populations in cities around the world and despite impacts from climate change (e.g. longer droughts).
The paper focused primarily on impacts to international cities and found that nearly one billion people may have access to less than 2/3 of a bathtub per day of water (less than 100 liters). The World Health Organization sites 100 liters as the minimum that a person needs each day.
For context, the typical American uses 2 to 5 times that amount per day. A full tub is about 150 liters, so if you used five times the minimum of 100 liters you’d be the three-bathtubber I was talking about!
In the video above, Rob invites us into his home (and his bathroom) to learn just how quickly a bathtub of water gets used up in a normal day.
