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.

Environment has always been changing in order to meet human’s desires of constructing more skyscrapers and estate. Such kind of human activities do make the Earth a better place to live, but they inevitably hurt the Earth to some extent. Although young as a student, I have been concerned about the harmful effects human bring to the environment for long. And this is the most important reason for why I come to UIUC and decided to major in environment economic and policy.

Nowadays, one significant threaten human causes to the global environment is water pollution. My father once told me about his hometown, which was used to be a bucolic town in the countryside. The town was surrounded by a stream which is so clear and clean that fish even a few meters down the surface could be easily seen. My father and his friends always went to swimming in the stream. However, a few years later, as crabs gradually became delicacy on the table, farmers there began to breed crabs as a new industry to stimulate the local economy. The steam was severely polluted and it became so smelly and disgusting that one could hardly approach.

Another harmful effect is air pollution. The wasted gases from the chemical factories or other industries are released unlimitedly and hence not only cause acid rain but also faded the blue color of the sky by darkening it. The exhausted gases spread out by the vehicles result in increasing tiny dust particles in air and act as a major cause to various illnesses concerning lung and respiratory systems. Therefore, we may see that human activities generate serious problems like this and finally harm ourselves.

Lastly, the most significant and urgent problem, which should be paid intense attention to, is global warming. Due to human’s deforestation in order to grow food and the excessive release of carbon dioxide, the atmosphere is continuously kept warm. Thus greenhouse effect emerges and the Earth faces gradual increase in temperature annually. As a consequent, the ice cap in both poles will melt, which might lead to a 10-metre increase in world average sea level. If all melt, the number will be 66 which mean that most of the Earth will be submerged. Animals like polar bears and penguin will lose their natural habitats forever. Human themselves will suffer from the extreme temperature and climate change.

An eye for an eye, an ear for an ear. If human persistently harm the Earth, the Earth will definitely punish human beings by exerting the detrimental effects on human. Thus, everyone has the duty to consider more about our existing Earth. Live it, love it and care about it.
