When the human was sleeping at night, the plates started moving. People were waken up and ran outside the house. They couldn't stand that several earthquakes hit often. In summer, the temperature becomes higher and higher than before. People stayed in the air conditioned room instead of going outside. The air-conditioned produced something that could ruin the ozone. That caused more and more sun radiation shoot into earth. Because of it, a lot of animals and plants couldn't bear. Above all, humans will be the most serious victim. What is to be done? This question has been hiding in our heart. Most of us been have not face these problem, including the government. They just only discussed these problems, but taking action seems to be difficult for them. Every country wanted their economy and technology to be on the top of the world. They ignored the environmental topic Keep ruining the earth; it's hard to stop them from doing it. For the citizens, we should be active doing some effective things to protect our earth. These days, a lot of scientists conduct experiments about these issues. They said that floods drought and other extreme weather are becoming more frequent the next ten years. They also warn that there will be more and more earthquakes hitting along the coast. The worst of all, the iceberg in the North Pole melt and the sea level continued rising. That causes a lot of dangerous problems. The habitats will disappear. At that time, the human will extinct. In order to prevent this from happening, we should do something to help the people living with us. We can take the public transportation as much as possible. This could reduce the emissions. Some people plant the trees to protect the ground. With the popularity of environmental protection awareness more and more people begin to rethink the connection between humans and the nature. We should make an effort to reduce the amount of trash and conserve energy in order to maintain a sustainable earth. It is no use only doing these things by citizen. The government has to sign the international agreement to protect the earth. Some order countries even spend a lot of money in order to reserve the environment. They don't want to see the terrible thing happen on human. We could eat vegetables instead of meat almost every day. If people on earth all can do it, I think the earth may change much easier. Our earth is a beautiful environment. We couldn't ruin it at all. All we have to do is giving back earth a harmonious ecology. This is what has to be done.
