In modern life, everything changes gradually, including technology, life style and climate, etc. The most important thing about our life is climate, because it is related to our life. In recent decades, climate has changed quietly and made a lot of influences on our environment. The summer and winter have been longer than ever, and the climate of many places changed abnormally. Because of the abnormal climate happening in the whole world, more people value the importance of a change of weather in these years. The experts from the whole world gathered to discuss what is to be done in the future. The urgent problem is that the sea level rising result from the high temperature, because the high temperature results in the melting of the iceberg at North Pole and South Pole. About ninety percent water is stored underneath the ice at North Pole and South Pole, So the melting of ice will make sea level rise and wreck the low island and the coastal earth. One of the most important causes which result in the sea level rising is too many emissions of carbon dioxide, so what we should do now is to cut down on the emission of the carbon dioxide immediately. As a citizen, I don’t have too much influence on the society. It is hard to imagine that a small act like dropping some litter on the ground can seriously affect the environment, but it can. That is because that all these small acts add up. On the contrary, some easy acts also can help the world a lot. In my opinion, there are some things that we can do in our life in order to protect the environment. First of all, we can choose the less packaged things when we are shopping. Even though the well-packaged things look more attractive, they also create more pollution and emit more carbon dioxide indirectly. Second, we should do our best to conserve electricity. Turn off the electronic equipments and pull the plugs when they are not being used. Most of Taiwan’s electricity was generated by fire power stations, so saving electricity also can decrease the emission of carbon dioxide. Third, we should avoid using disposable things which are usually harmful for our earth. In their production procedure, many chemical substances are added in products. Last but not least, we can choose the vegetarian diet instead of meat. A large part of ejections of greenhouse gas comes from animals, so we can reduce the emissions of carbon dioxide by eating less meat. Although it is impossible for one to save the environment, we can protect our earth if we do it together.
