They cover only about of the world’s land, but are home to more than half of all living things. These dense forests are full of life, from tiny insects to large animals, and from small plants to tall trees. The rainforest has different layers. The top layer is called the emergent layer, where the tallest trees reach up to 70 metres. Below that is the canopy, a thick layer of leaves and branches that stops most sunlight from reaching the layers below. Next is the understory, with smaller trees and bushes. The bottom layer is the forest floor, where only a little sunlight gets through. Many rainforest animals have special skills to live in their layers. For example, sloths hang from the canopy branches. Their long claws help them stay there, and their slow movement helps them save energy. Toucans have big beaks to reach fruit on thin branches that can’t hold their weight. On the forest floor, jaguars use their spots to hide in the shadows while hunting. Rainforests are important for the whole world. They take in carbon dioxide (二氧化碳) and give out oxygen (氧气), which helps keep the air clean. They also help control the world’s weather. But rainforests are in danger. Every year, large areas are cut down for wood or to make space for farms. This destroys the homes of many animals and plants, and may even change the world’s climate.
