Topic 29 Has human harmed the Earth or made it a better place?

Some people believe that the Earth is being harmed by human activity. Others feel that human activity makes the Earth a better place to live. In my opinion, human activity is damaging the Earth. There are many reasons for my perspective as follows.

First, human activity causes many kinds of animals and plants to disappear. Today many species of living beings died out or near died out. We only can see some animals in the zoo because in nature they have disappeared. Human beings have been using their brains and machines to remake nature for many thousands of years. We use the habitats of animals and plants. We eat their food and eat them as food. Because animals and plants cannot grow fast to satisfy human beings, we cannot see them today. If some animals are dangerous to us, we kill them with our weapons. If meats of some animals are delicious, we eat them. No animals can copy with human being.

Secondly, human beings cause pollution to the Earth. I remember when I was young; I drank water from the river and stream. Today we can only drink bottled water bought from the market, because natural water is polluted by human activities. Air in some countries is polluted very badly, so many people died of lung cancer. I saw some reports that says in London people could not see each other clearly in a short distance in the morning because of much smoke and fog.

Finally, population on the Earth exacerbate rapidly. Human beings need more food and shelters because of increased population. More food and houses mean more needs from the Earth. Thus people need to cut more trees to build houses. People need to plant more vegetables and feed more cattle, so they demand more lands from the nature. Thus people are destroying more forests and natural lands. The living beings are losing their habitats.

Take into account of all factors I think the earth is being harmed by human activity. Today we cannot breathe fresh air and drink natural water. We have not enough places to live. We worry about our health because of pollution.

Topic 29 Has human harmed the Earth or made it a better place?

When it comes to what human activity made the Earth, tradition has human activity that damaged the Earth. Nevertheless, although human activity has caused some damage to the earth, our Earth has certainly been turned into a much more beautiful world than it was centuries ago.

First of all, due to the development of human productivity made possible by science and technology, we now enjoy living conditions that our ancestors could never dreamed of. Nowadays, we use machine to plant crops, use synthetic fodder to feed livestock, use water conservancy project to generate electric power and so on. In term of substantive level, no other reasons in my decision is more crucial than the one above.

Furthermore, the use of machines has greatly improved our working conditions, enabling us to enjoy more leisure and entertainment. Tape recorder's invention serves as a typical example. They are small and have well sound quality. We can take it everywhere with us and the tape recorder has a valuable argument that it enabled me to listen to my favorite music wherever I want in a variety of different formats.

Of course, it should be admitted that human activity has resulted in the environmental crisis, which I believe we could overcome with the help of science and technology. The majority holds the opinion that human activity carries lots of pollution, which made the air quality worse, and endangered species increases everyday. On the surface, these seem to be terrible. However, people are taking a fresh look at it that they can be improved sooner because of science and technology development.

In short, human activity makes the Earth develop. It is difficult to imagine how the world will be without human activity. Similarly, a person who does not use machine in peacetime that cannot get anything done. Therefore, after pondering this question on many occasions, I believe that human activity makes the Earth better and beautiful and a great place to live!
