Some people believe that the Earth is being harmed (damaged) by human activity. Others feel that human activity makes the Earth a better place to live. What is your opinion? Use specific reasons and examples to support your answer. 「范文」 Human Activity and the Earth There is no doubt that human activity has an effect on the planet. We see the evidenceof mankinds endeavors all around us. While some of mans accomplishments， such as the building of transportation systems and the consistent supply of potable water， have made Earth a better place for people to live， they have not come without cost. Overall， it seems that human activity harms the Earth more than it benefits it. For example， the transportation systems that benefit mankind also create pollution and use up valuable energy resources. While we cannot do without transportation these days， we cannot ignore the fact that it has an adverse effect on the planet. Furthermore， those advances that benefit people do not benefit all the life on Earth. Deforestation endangers many animals， and mankinds great thirst for water and other resources leads to the extinction of many plant forms. In addition， accomplishments such as the supply of potable water to a community are only responses to problemsthat mankind created in the past. It was man that made the water unfit to drink in the first place. Finally， the damage that human activity causes will eventually have a negative effect on people. They will also suffer the effects of pollution and diminishing natural resources. |
