2. Layered Like a Cake: Rain forests are divided into four different layers—the emergent layer, canopy, understory, and forest floor—with different animals and plants living in each one.

3. Home to Half the World's Plants and Animals: Even though rain forests cover only a small part of the Earth's surface, more than half of all the world's plant and animal species live there!

4. The Lungs of the Planet: Rain forest trees act like giant green lungs by taking in carbon dioxide from the air and pumping out fresh oxygen for us to breathe.

5. Medicine from the Trees: A huge number of the medicines we use today come from plants found growing wild only in tropical rain forests.

6. Singing with Colorful Birds: Rain forests are famous for being noisy, colorful homes to creatures like toucans, bright parrots, tree frogs, and playful monkeys.
