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.

Some people say that human activity is necessary for them to live on the Earth comfortably, while others insist that we have to limit our activity for the Earth. In my opinion, the latter one is true for the following reasons. Firstly, human activity has been causing the climate change. Secondly, people often discard their garbage into the ocean, mountains, and so on. This essay will discuss these reasons in further detail.

One of the negative sides of human activity is that it brings up the climate change. Global warming leads to melting ice of mountain, raising the surface of the sea, and significant damage on the crop. For example, as the surface of the sea rises, it is expected that many coast areas will be sunk. Of course, this sinking will cause the devastating damage from the residential side, the natural environment side, and so on. It is also true that the climate change has not been proved enough by scientists, but it is too late once it happens. So, we have to pay attention to limit our activity for keeping the Earth as a good place for human beings.

Another demerit of human activity is that they throw away a lot of garbage. They abandon their trashes into the ocean, mountains, islands and it destroys the natural beauty. For example, Mt. Fuji is one of the most famous mountains in Japan for its beauty. However, it is also known for its filth. This is because many tourists litter while climbing, and many trashes have been left. Not only from the perspective of beauty, but also from the perspective for the natural environment, disorganized trashing is the problem. For example, many birds eat garbage wrongly and suffer every year.

In conclusion, I think human activity harm the Earth because people are changing the climate by its activity. Furthermore, they have been making the environment dirtier by its arbitrary behavior. So, to keep the Earth beautiful, and above all to keep the Earth sustainable so that our offspring can live in, we will have to rethink about our activity.
