托福考试作文范文参考：
People have learned how to turn wild natural areas to farmland， how to exploit minerals to adapt their needs， how to build roads and houses to expand their territories. People continuously improve their knowledge and develop technologies to improve their lives. It is undeniable that these activities of human beings make their lives better than ever before. Nevertheless， those activities also cause side-effects to the Earth because of pollution， deforestation， and exaggerated natural resource exploitation.
Nowadays， pollution becomes one of the most concerned problems. Because of the increasingly expanded factories， the industrialized areas， the burning of population etc， too much pollutant spills out everyday. Consequently， all of these things cause bad effect to the Earth. The purity of atmosphere is reduced seriously， the Earth is continuously warmed up， and ozone layer is holed.
Additionally， forest is asking for help in desperation. For last few decades， the forest areas have been reduced to 50 percent because of human deforestation. Green forestland of the Earth can be compared to the lungs of human. How healthy you are if your lungs are trespassed. I am sure that you will get more difficult with aspiration； as a result， your health will be affect badly. From this example， we can infer that how serious problem our Earth has to face with. I wonder how long it can endure.
Researchers show that the natural means is limited， but today， they are exploited so increasingly to adapt infinite human needs that someday， all mineral can be ended up. Because of serious pollution， alarming deforestation and progressive mineral exploitation， the ecosystem becomes unbalance. Consequently a lot natural calamities happen each year such as flood， hurricanes. A lot wild living creatures are exposed to narrow place of shelter and lacking foods. For these reasons， the Earth will become unhealthy.
In conclusion， the human beings harm the Earth. Human beings as well as their dear planet， the Earth， have been badly suffered by what caused by humans themselves. I hope that humans are soon aware of those problems so that they can have suitable policies in order to not only improve their lives but also keep and maintain the Earth fresh and green.
