Nearly all living things depend on Earth's land and its resources to survive. But did you know that people do many things that hurt the land? The damage sometimes destroys forests, which are home to diverse ecosystems and are important in producing oxygen and water. And in many parts of the world, damaged land produces less food, less wood, and less of many things that people need. We must join together in the quest to find better ways to use and take care of Earth's land. With engaging text and eye-catching images--plus a special Going Green section--this book tells you all about Earth's land and what you can do to protect it.
