They are often called the "lungs of the Earth" because they produce a large amount of oxygen. Rainforests are home to more than half of the world's plant and animal species. They also play a key role in controlling the global climate. In a rainforest, trees grow very tall. They compete for sunlight, so they grow upwards quickly. The leaves of these trees form a thick canopy that blocks most of the sunlight from reaching the ground. As a result, only a few plants can grow on the forest floor. Rainforests get a lot of rain every year — up to 400 inches. The rain and warm temperatures create a perfect environment for plants to grow. The trees in the rainforest can even make their own rain. Water comes out of the leaves and forms clouds. These clouds then rain on the forest. Unfortunately, rainforests are disappearing quickly. People cut down trees for wood, farming and building. This not only destroys the homes of millions of animals but also affects the global climate. Many organizations are working to protect rainforests. In the future, we must find a way to balance human needs with the protection of these precious forests. ( )1. Why are rainforests called the "lungs of the Earth"? A. Because they are very big. B.
