You can change the world. Here's how.

Our climate is changing and human actions are the cause. Maybe you don't know why, or what to do about it. We do. In fact, we wrote a book about it (this book, the one in your hands). We'll harness your green intentions and push you beyond turning off the AC every once in a while. It's all in here:

• how to keep the planet healthy
• facts and info
• real-life stories
• suggestions and challenges
• eco-tips from MySpace users around the globe.

Everybody who submitted a tip got their username in this book, btw.

Each of us has the power to make a difference—open this book, arm yourself with knowledge, and start now. (Seriously. What are you waiting for?)
