March 29 is Earth Day. Everyone on earth should care about and protect the earth!

The earth has warmed by about 1（华氏度） over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.

First, greenhouse effect （温室效应） is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate （气候） change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island,100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999.Scientists say that the seas can rise by nearly one metre by 2100.

People can affect the earth’s air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

A.learn more about the earth B.make full use of the earth

The largest animal ever to live on Earth is the blue whale（鲸鱼）. It weighs(重) about 80 tons-more than 24 big elephants. It is more than 30 metres long.

One cat fell off 32 floors onto the street, but it was just hurt a little. A bear can run as fast as a horse.　 A new-born panda is smaller than a mouse and weighs about 100 grams.　 Elephants are the most careful animals in their love.

Our Earth is welcoming a great day soon. April 22nd is Earth Day. It’s a day for us to take care of the Earth. So what can we do to help? Around the world, many cities and countries find ways to make themselves green.

Chicago is famous for its green roofs(屋顶). There are plants on these roofs. These plants can keep much rainwater. Later, the water goes back to the air to make the city cool and clean.

Singapore City is home to the first zero-energy (能量) building in Southeast Asia. Zero energy means the energy which a building makes can’t be used up (被用光).

Curitiba, Brazil, has buses called BRT. BRT runs on special lanes (车道) so it will always be on time, even there is lots of traffic. Thanks to BRT, the air in the city is very clean. Today, many other countries have BRT, such as China and Mexico.

We only have one Earth, so we have to take care of her.
