人类活动与地球(Human Activity and the Earth)
There is no doubt that human activity has an effect on the planet. We see the evidence of mankind’s endeavors all around us. While some of man’s 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 al the life on Earth. Deforestation endangers many animals, and mankind’s 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 response to problems that 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.
In conclusion, it seems apparent that man’s activity benefits primarily himself, not the Earth. Moreover, those benefits are only short-term advantages, and man will also suffer the negative effects of his activity in the future. The Earth does not have an inexhaustible supply of resources, so every effort should be made to conserve resources and limit the impact of human activity on the planet.
