Endangered Polar Bears by Chemical Materials

Argument Essay

Since the Industrial Revolution, we have used various and lots of chemical materials for getting better high quality life. These were obviously necessary for us. For example, they have given convenience, have protected us from the disaster, like fire, and have been elevated our life. Moreover, they could be a technological leader in this world. However, nowadays, these are threatening our environment and human as us. According to this issue that I mention, there are three main chemical materials which affect pollution in the Arctic and the mammals such as polar bears. Thus, I am going to mention why we have to stop using them and how we solve these problems.

First, there are three main chemical materials which harm environment included polar bears. They are PBDEs, DDT, Freon Gas that have been actually useful chemical materials for getting high quality life and protecting our life since the Industrial Revolution. However, they are destroying strongly polar bears. For example, PBDEs, which used in an insulator, can make polar bears to be hermaphrodite which has both female and male sex organs. Next, DDT, which protects crops from the insects, can make polar bears to palsy the central nerve. Finally, Freon Gas, which used in the refrigerator, freezer, and the air conditioner, can destroy Ozone Layer. It is called Global Warming. In fact, ice in the Arctic is melting because of Global Warming, so that many polar bears lost their ground, and they have to swim long distance for finding another area for surviving.

Second, we have to stop using these chemical materials. It is true that they have helped developing technology and given to us convenience life. I have no idea how our life is good or not if we didn’t have chemical materials. However, they are affecting badly polar bears, like that I mention. Also environment is pollutant by chemical materials. If environment can be purgation, we must wait centuries or forever. Therefore, now we know that chemical materials harm environment including polar bears, so that we have to stop using and making chemical materials anymore.

Third, we have to consider as soon as possible inventing materials which does not affect harmfully environment instead of theses chemical materials. We cannot live without them. In summer, we really need an air conditioner, and a refrigerator. Moreover, during burning fire, we can survive because of PBDEs. Also, farmers can harvest high proportion of crops because DDT can protect crops from the insects. However, we have to eliminate them for protecting polar bears. Therefore, the government and the organism of environment and science have to invent alternative energy such as solar energy, hybrid power, and wind power instead of chemical materials.

In conclusion, we have to protect polar bears lived in Arctic. Do you know why? Are polar bears just our friends? No. Actually, these problems by chemical materials are not only polar bears, but also our problems in near future. Nobody knows that we can be hermaphrodite by chemical materials, our land can be soaked in the sea, and we can get a disease from DDT. Nowadays, our job is to keep our environment that we live in.
