Ellen DeGeneres, Robert Redford, Will Ferrell, Jennifer Aniston, Faith Hill, Tim McGraw, Martha Stewart, Tyra Banks, Dale Earnhardt, Jr., Tiki Barber, Owen Wilson, and Justin Timberlake tell you how they make a difference to the environment.

Inside The Green Book, find out how you can too:

- Turn your thermostat a degree lower in the winter; if every home in America did it we'd save enough energy to power all the homes in Iowa for one whole year!

- Take a shorter shower; if Americans subtracted just one minute from their daily showers over the course of a year we'd save twice the amount of freshwater that is withdrawn from the Great Lakes every day!

- Reuse ribbon and wrapping paper; if two-thirds of Americans each saved an arm's length of ribbon this year, we could tie a bow around the earth!

We all need a manual for green living!

It's a great read and will help you learn simple ways to practice saving the environment! : )

Want to live green and eco friendly? This is the book! Flip some recycled pages and learn about living green with this great book.

New York Times Bestseller's everyday guide to saving the planet one step at a time… called The Green Book by Elizabeth Rogers and Thomas M. Kostigen. There's a foreword by Cameron Diaz of all people...

I recommend this to all my greeny pals: Elizabeth Rogers very cleverly pairs virtuous tips with essays from entertainment luminaries (Ellen! Martha!). Smart and useful. And fun.

This book is printed on recycled paper and lays out, by genre/area of life, different ways to reduce your eco-footprint and why you would want to. The book is an easy-to-read guide and very friendly. A definite must-have for those looking to make the simple steps into the green world.

Go green! Environmental matters get the star treatment in The Green Book. Authors Elizabeth Rogers and Thomas Kostigen address the fact that Americans endanger the balance of the ecosystem by the amount of waste we produce, the amount of water we use and the amount of energy we consume. Celebrities, including Robert Redford, Ellen DeGeneres, Jennifer Aniston, Faith Hill and Dale Earnhardt Jr., contribute observations and suggestions for living green. In the hope that the glamour of the A-list will make discussion of environmental challenges more palpable, Rogers and Kostigen establish 12 aspects of our habitat, such as home, work, and school, and suggest better lifestyle choices in each arena. Small adjustments in the way we consume and dispose of resources add up to significant and positive environmental effects. Illustrating the results of green actions with descriptive rather than numerical analyses, Rogers and Kostigen write, for example, that if everyone in the U.S. used one less paper napkin per day, in a year's time we would have saved one billion pounds of landfill waste. This is a truly outstanding resource, and one you won't want to live without. The Green Book offers hope and practical suggestions for a greener future!
