  The environmental pollution is worse and worse /more and more seriously today. Water is polluted; we have no clean water to drink. Many trees are cutting down, some animals is getting less and less. Some factories are pouring dirty air in the sky, the population is increasing faster and faster, resources are getting less and lessetc. Not only does it affect our lives and health, it but also has a great affection in the future. People's health has been greatly affected by air, noise and water pollution. Many people died of diseases. In order to live a better life, we need protect our world.

  We shouldnt throw away rubbish everywhere. We want to recycle, reduce, reuse things .Dont waste things. This saves money and reduces pollution. Use things for as long as possible. We dont use plastic bags. We must plant more trees and stop the people cutting them .We hope our world becomes more and more beautiful.

拯救地球   地球是我们人类共同的家园,人类只有一个地球。“低碳、环保”已成为当今时代主题。目前,我市英语学会准备在全市中学生中开展以“Save our earth”为主题的英文征文活动。根据以下三个方面的提示,写一篇短文参评。要求:1.重要性:只有一个地球   2.主要问题:污染、疾病、灾难  3.措施:停止污染、保护大自然

  Lets Do Something to Save Our Environment

  It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

  So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water. Second, we should save energy, such as less turning on the lights and turning off the lights when we leave;Do more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.

  Lets act now from everything to save our environment. Dont let our tears be the last drop of water in the world!
