About overfhishing

In this rapidly changing world, the population in the world is getting bigger and the ramification caused by human being is also getting bigger. The resent biggest problem is might be food shortage, and one of the problems that are directly related to food problems is the overfishing problem. It is often said that it is okay that people keep overfishing because it serves more food for human. However, I totally disagree with doing overfishing is necessary for two reasons; overfishing cause bad effect not only to environment but also to human.

To begin with, overfishing destroys environment. As we saw in the presentation, if fisher does overfishing, they usually kill more fishes, such as other species, breeder, and young fishes, than what they actually want. This offsets other ramifications, especially in food chain. For example, if one species, A,’ population became smaller, another species, B,’ population which is eaten by A would have become unreasonably bigger.

Also, overfishing affects human life. This is because people could lose their job, especially fisher man, if the population of fish is getting smaller. For instance, according to the study conducted by Canada, the fisher man job has been decreased in past several years because of decreasing amount of white fish in the ocean.

To sum up, people should avoid doing overfishing for keeping environment nice and human. It might be hard to change one time, but if we start to pay attention about this issue, it is not going to take long.
