To protect the environment, we are on the way. Here are a few things we can do.

  Unwanted gifts? Give them away!

  Have you ever received a gift that you didn’t like? Did you throw it away? If so, you can have another choice now. Two British companies hopes people will give away their unwanted gifts to them. And they will resell the gifts to raise money for the poor. In this way, the gifts can be refused and have a future life. And people can make a difference to the world.

  Wear the trousers that reduce(减少) pollution!

  A chemistry scientist and a fashion designer (时装设计师) have created a new kind of trousers. The trousers are made of a new material which can help reduce air pollution around us. Scientists have tested the material. The result shows that it isn’t harmful to human. This new kind of trousers may appear at the market in two years. Professor Ryan said, “If thousands of people wear the trousers, the air quality will be improved.”

  Plant trees with Felix

  Felix Finkbeiner, a 14-year-old German boy, is not famous as a child actor but an environment hero. At the age of 9, Felix got the idea that children could do something to protect the environment. So he started a club. Felix soon got support from children all over the world. Some of them have become his good friends. The club has an aim of planting 212 million trees. They have planted over 3.5 million trees all around the world. Felix said, “The answer to controlling global(全球的) warming is trees—lots of trees!”
