If you can only read and reference one green thing, make it this book: an easily comprehensible, clearly presented source for green living and conservation. Everything you need to know is right here at your fingertips. Unlike a lot of other overwhelming environmental guides on the market, this is green decision making in bite sized pieces. With chose it/lose it comparisons throughout, now it's simple to figure out it's worth switching to a green detergent, what kind of plastic your sports bottle is made of, or which fish is safest to eat. Rather than spending time trying to figure out how best to conserve, recycle, and protect the environment, use this book and devote that time to making the difference.
