It is not possible to tell the importance of forests in just a few words. Forests affect(影响) our daily lives in so many ways ，even in the busy noisy city center.
Just think about your life today: Do you have your breakfast? Read a newspaper? Turn on a light? Travel to work in a bus or car?Do your homework ? Write on your notebook? Clean your hands with a tissue （纸巾）?
Forest products are everywhere in our daily lives. All the activities above(以上) have something to do with forests. Some are easy to point out-fruits, paper and wood from trees, and so on. Others are less obvious(明显的)-they help make daily products like medicine. They not only help make our lives more convenient(方便的)，but also make our Earth more beautiful and comfortable.
Forests help protect the sea, and the Earth is in good health because of them.
However, we are losing them. Over the past 50 years, about half the world's forests have been lost. The most important reason for that is people's activities like polluting the environment and cutting down trees.
When we destroy(毁坏)the forests, we not only lose the trees，all the animals in the forests will also lose their homes. As this goes on, it'll be harder and harder for us to survive(生存)on the Earth.
