From brilliantly colored birds and wild elephants to towering trees and exotic flowers, rain forests are home to more than half of Earth's plants and animals. People living in rain forests depend on this vast array of life, and Earth itself relies on the world's rain forests to keep our climate and atmosphere in balance. But rain forests around the world are under threat. Once rain forests covered nearly 14 percent of Earth, but now they have shrunk to less than half that size. People around the globe are joining the quest to save rain forests. With engaging text and eye-catching images—plus a special Going Green section—this book tells you all about Earth's rain forests and what you can do to protect them.
