I've found the greatest new book: The Green Book, The Everyday Guide to Saving the Planet One Simple Step at a Time.
It's full of hundreds of small choices you can make to have a big impact on the environment, such as:
Refuse ATM Receipts: Most ATM's now give you the option of getting a receipt instead of automatically giving you one. If everyone in the United States refused their receipts, it would save a roll of paper more than two billion feet long, or long enough to circle the equator fifteen times.
I love this book and will use it personally as well as professionally! Look for more neat tips on upcoming blog posts.
