高中英语演讲稿范文带翻译
Today, economy is advancing at a fast pace and together with it, the climate. Greenhouse gases is getting more and more and the world ，with its rising temperature, is having a 'fever. Due to the icebergs melting rapidly, the sea level is increasing and who knows when it will drown some of the islands and wipe out civilizations ? Natural disasters are all taking place more often than not. So, is there no help at all? What can we do to slow down the pace of global-warming? First of all, we can use the clean energy which will not pollute the air , the ground or the sea. Some examples are the solar energy, the wind energy and the wave energy. Secondly, we can plant more trees . One way in which the tree can help is that it takes in carbon dioxide , a greenhouse gas, and releases oxygen instead. Isn't this killing two birds with one stone? Lastly, we can reduce the use of cars and walk instead. The cars let off exhaust gases and pollute the earth. If we use our legs instead, we can do our part on saving the earth and even exercise at the same time!
