Nowadays, people are living in a planet which is now “having a fever”. The global surface temperatures are likely to increase by 1.1 to 6.4 °C between 1990 and 2100. As the issue is becoming more and more serious, more and more scientists are learning about its causes and efforts. The biggest cause is due to more and more greenhouse gases are produced and put into the air. As the development of people’s standard of living, more and more people have their own cars. Even though having a car can make the life easier than before; it also bring a huge problem at the same time. Cars can only use 25% of their gases and the rest are putting into the air as CO2. Another big sourse of CO2 is from Power Plants. CO2 emissions stem from the burning of fossil fuels for the purpose of electricity generation. Due to the rising of CO2, the earth is “having a fever”. As a result of the earth’s “disease”, people have to face lots of terrible problems. The high temperature can cause many heart diseases, influence the ski industry and brimg the extreme weather. Therefore, for our generations, les us try our best to make the earth cool by using energy-saving lights,  buy a clean and efficient car and plant more trees.
