The article “Environmental Impacts of Ocean Fishing & Fisheries” demonstrates that human activities have severely affected the marine life on the Earth’s oceans. Fisheries may be necessary for providing food and for the economy but they are causing huge damage to the environment. Environmentalists are warming us that if the fisheries continue to expand worldwide, negative impacts would dramatically increase and interfere with the trophic level within the ecosystem. Moreover, the author mentions that ocean fish stocks are constantly declining in the United States, and it is predicted by a relevant study that, at prevailing trends, the world would run out of wild seafood in 2048. Furthermore, our activities have been depleting the ocean water quality. The author shows that there are various ways by which human activities negatively impact oceans water and fish habitats. Overfishing is one of them: it occurs when the fishing sector catch more fish than what can naturally regenerate through reproduction. Also, pollution and contamination contributed to the degradation of oceans water. We are dumping our wastes into the oceans (industrial run-off, toxic waste, radioactive waste, waste from agriculture activities). Marine traffic generates tons of hydrocarbon a year (burning fuel). In the article, it states that the two major causes of loss of ocean salmon are the high harvest rates and the building dams on rivers. Furthermore, one way we are contributing to the loss of ocean fish species and the marine life is by using damaging methods that affect natural habitats and ecological balance of the oceans. Some of those methods are explosive fishing, cyanide fishing, and bottom trawling. The article proposes some ways to improve wild fishing, such as promoting good fisheries management, combating illegal fishing, cutting down destructive fishing practices, and developing and practicing new technologies.
In my opinion, I understand that wild caught fish are an important protein source but I believe that the current fisheries rules are no efficient and the fishing capacity is not enough controlled/enforced and limited. Moreover, I think that fisheries should not take more species than populations can sustain, and I also believe that the methods of how we fish really matters. It requires a very good management to solve the problem of overfishing and the government should do something about it.
