About

What covers a tiny fraction of Earth’s surface, but is home to more than half its plant and animal species? Tropical rainforests are the most biodiverse places on the planet. From the emergent layer to the forest floor, rainforests teem with life, thanks to their year-round warm temperatures and plentiful precipitation. You’ll find out about how species in this biome are specially adapted for life there, and how rainforests help all life on Earth—including humans. But some human activities are threatening rainforests, and causing rapid extinction there.
