It is obvious that along with human activity increasing, the Earth has changed a lot, especially for recent tens of years. However the issue that human activity eventually brings advantage to the Earth or not, is still a controversial one. Majority considers that human activity is making the Earth a better place to live. Nevertheless, I take an opposite view that human do more damage than benefit to the Earth. My arguments for this view are listed as follows.
One of the most crucial reasons for my propensity is that wastewater, exhaust gas and waste residue produced by human, are seriously threatening the environment of the Earth. The more rapidly human expand, the worse the environment of the Earth is. And because people don’t give sufficient notice to this problem, the destruction of the environment still keeps on. The city I live in is just in this case. Five years ago, I came to this city and was deeply abstracted by its beauty. Every day I walked along the clear stream in the dawn, smelling the fragrance of grassland. The city was so charming that nobody could refuse it in that time. However, in the following five years, a great deal of waste was yielded, while people strived to promote the economy of this city. Perhaps citizens will loose a comfortable living circumstance forever.
Another essential factor why I take my view is that wild plants and animals die out at the velocity faster than usual, at the time the development of human society speeds up. We may wonder why and how it happens. By carefully researching, scientists get the conclusion that excessive activity invade the areas belonging to wild animals before, destroy the circumstance that wild animals and plants lie in, and eventually break up the balance of nature system. All habitants living on the Earth but human suffer the disaster brought out by human nowadays. Nevertheless, someday human will be published by nature either.
Admittedly, we cannot deny the advantage brought by human either. To some extend, the Earth indeed becomes a more civilized place to live, such as electricity, high buildings, kinds of machines and so on. Whereas, we cannot neglect the disaster human activity brings about.
From all the analysis above, it is not difficult to conclude that human activity brings more harm than benefit to the Earth, and must give a high light to the environment problem.
