The Importance of Trees
Trees are vital to life on Earth. They absorb carbon dioxide from the air and release oxygen, which humans and animals need to breathe. Because trees provide oxygen, they help keep the air clean and healthy. Trees also help prevent soil erosion. Their roots hold the soil in place, so when it rains heavily, the soil is not washed away. This is especially important on hillsides. Many animals, like birds and squirrels, make their homes in trees, which means trees provide shelter and food for wildlife. Unfortunately, deforestation, the cutting down of many trees, is a big problem. When too many trees are cut down, there is less oxygen in the air, and more carbon dioxide, which can lead to climate change. Also, without tree roots to hold soil, heavy rains can cause landslides.
