What covers less than 10 percent of the Earth’s land yet contains about 50 percent of all its animal, insect, and plant species? Any ideas? It’s a tropical rain forest. To help your students learn more about this incredibly important ecosystem, we are featuring 5 Topics for you to share.
The world’s largest watershed (by far) is the Amazon Basin, which covers over 2.6 million square miles (40 percent of South America) and funnels water from over a thousand tributaries in eight countries. It all flows into the mighty 4,000-mile-long Amazon River, which has a phenomenally powerful flow. In fact, the Amazon carries more than one-fifth of all the river water in the world.
More than half the world’s species of plants and animals live in rain forests. When the forests are cut down, the plants die, and the animals lose their homes. That’s why many rain forest animals and plants are endangered. Most scientists agree that 100 species of rain forest animals become extinct—every day!
Located in a belt around the equator, rain forests are a riot of life, with plants growing non-stop year-round.
