These tips are from The Green Book:  The Everyday Guide to Saving the Planet One Simple Step at a Time.

Forget the Receipt

Don't take an ATM receipt.  ATM receipts are one of the top sources of litter on the planet.  If everyone in the U.S. did not take a receipt from the ATM, it would save a roll of paper more than a billion feet long, or enough to circle the equator 15 times.

Commercial car washes use up to 100 less gallons of water to wash a car.  They often recycle and reuse rinse water.  If everyone who washed their own car chose to go to a professional car wash just once, up to 8.7 billion gallons of water could be saved and several billions of soapy, polluted  water could be diverted from rivers, lakes and streams.
