Rainforests are some of the most beautiful places on the Earth. Tall trees grow high into the air. Millions of different kinds of animals run and play under the trees. Rainforests cover two percent of the earth, but they have over 50 percent of the world’s plants and animals.

It takes at least one minute to plant a tree. In that minute, 60 hectares (亩) of rainforests are destroyed forever. Six kinds of animals become extinct; they will never be seen again.

Every second, people cut down one hectare of rainforests. They use the trees to make things like paper. Because they cut down the trees so fast, the rainforests become smaller and smaller. By 2030, they will all be gone.

You can help save the rainforests. Try not to use too much paper; then paper companies will not cut down so many trees.
