Take a journey through the heart of the Amazon rain forest to discover why it's so important for life on Earth.

Even though rain forests take up less than 10 percent of Earth's land, they are home to more than half the world's plants and animals. In this adventure, readers climb aboard a river boat and tour the Amazon with a local guide. Observe howler monkeys, harpy eagles, and other wildlife as you discover how the planet's largest tropical rain forest became endangered, and why it's up to us to protect it.
