A crash course in changing the world.
One promise I made is to take less than 10 minute showers, preferably only 5 minutes. It doesn't seem like much but every time you shower that is gallons per minute of water that is going out the drain…literally. http://www.alternet.org/story/141751/how_much_water_do_you_use_here's_some_quick_numbers
This link has some great statistics to show that 10 gallons are used in a quick 5 minute shower alone, even more depending on what nossle you have.
