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 centre. 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?

Forest products are used in our daily lives. All the activities above 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, 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 trees.

When we destroy 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 on the Earth.

My daughter Amy is seven and she is welcome in our family. She comes to me one day. She has some cards. They are green, purple, yellow, blue and black. But she asks me for a red one. I don’t know the reason（原因）but I help her find one in my room. She thanks me and says her favorite（特别喜欢的）color is red.

The next day in the morning, she puts（放）a red ruler, a red pen, a red pencil and a red eraser in her pencil box, and a red notebook in her schoolbag. Oh! She is crazy about red. After school（放学后）, she asks me for a red bed in her room. A blue bed is in her room, and it is nice. I know her favorite color is red, but I don’t think making everything（使任何事物）red is good.
