People live in the world for many years. The earth is affected by human activities. Some people believe that the world is being harmed by human activities. Other people believe that human activities make the world a better place to live. In my opinion, the world is being harmed by human activities. There are a lot of explanations supporting my opinion.
Firstly, human activities have harmed natural environment. Human activities have almost consumed all natural reserves. The scientists need a lot of resources instead of water, minerals and fuels. So we confront lethal problems such as being without water. Balance of ecology is harmed, because factories and people occupy a lot of places where plants and animals live. Gradually, people harm forests. If we do not realize these problems, we will lost environment for our living.
Secondly, there is the greenhouse effect. Humans destroy forests and increase the use of fuels so the gas of CO2 is released gradually. The greenhouse effect is very obvious. Due to the fact that, icebergs melt in polars, sea level star to go higher than before levels.
Last but not least, there is waste problem caused by products made of plastic by people. All kind of gadgets nowadays are almost made of plastic. After we bought it, we will throw away. Then, it will lay for years in the environment or it will be burned and turned into CO2.
In conclusion, human activities bring the world a lot of damages. Fortunately, people have recognized the point and I believe that the world will become a better place to live with our efforts. We should be more careful for a better world.
