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.
While the past few centuries have witnessed increasingly better quality of human life, human activity is doing more and more harm to the Earth. Natural resources are being depleted and pollution is being created as a result of development of technology. Natural areas are being damaged as a result of urban expansion to populate more people.
First, we harm the Earth by using more and more natural resources. If we fell too many trees at one time to build
houses and make paper, or if we cut down trees before they grow to maturity, they can hardly grow back in time. As worrisome as overcutting of trees is overfishing. With improved technology and greater drive for money, fish of all kinds are being over hunted, reducing the biomass of some fish to the verge of extinction. Whaling seems a most irksome issue. While most countries argue against it, some countries go whaling to extremes. We often take it for granted that we have unlimited natural resources and use them in a wasteful manner, bringing about great losses.
Second, we damage the Earth by producing pollution in all forms. Factories pollute water and the air. Vehicles pollute the air. Nuclear-related and electronic products are playing an increasingly big role in polluting the air, especially when we dispose of related waste carelessly. We take it for granted that Nature can help clean everything, but it can not.
Third, expanding towns and cities are taking up more and more land. As populations flood to cities, new houses and stores have to be built to accommoda
