Rainforest Layers Reasons to Save Rainforests Tropical rainforests are dense, mostly evergreen, broadleaf forests found near the equator in Latin America, Hawaii, Madagascar, Indonesia, Australia, Asia, and Africa. In true rainforests, it rains almost all year round and daylight lasts twelve hours every day. The air is always hot and steamy. Rainforests are crossed by streams and rivers and filled with a huge variety of plants and animals.
Tropical rainforests are the oldest kind of forest.
They have been growing on Earth for millions of years, longer than almost anything else. They are the richest natural places, with abundant plants and animals. Our oldest human ancestors probably lived in rainforests, and we still depend on them for many foods, medicines, woods, fibers, and saps. Thousands of kinds of trees, all different sizes, grow in the rainforest. Flowers, ferns vines, lichens, liverworts, mosses and algae grow there too.
