Overfishing: A Serious Issue

In this article, “Getting Serious about Overfishing” by the Economist, it is implied that our oceans are in more trouble than they have ever been. According to the article, we consume the most fish we have ever consumed. It is shown that in a study conducted in 2013, 32% of the world’s fish stocks were being exploited beyond their sustainable limit which is a lot and this is an increase of 10% since the 1970s. Although we overfish, other problems which affect the oceans are pollution and fertilizer run-off which causes big damage to the fish since it ruins their ecosystems. At this time the article mentions there is about five trillion pieces of plastic in the oceans and about 8 million are added ever year to this already extremely large amount. The increase of carbon dioxide in the atmosphere has also made it hard for the nutrients from the bottom of the ocean to rise and feed fish as well as plankton. It is also said that when the oceans absorb all of this carbon dioxide it increases its acidity which affects coral reefs as well as organisms who have shells since the acidity increases the chances of their shells dissolving. The article stresses that human impacts need to be reined in in order for our oceans to survive on for us to continue to benefit from its resources. It is also said that we would need to put more restrictions on fisheries and manage them better.

I personally find that our overfishing is become more and more of a problem and that our pollution is not helping any of it get better. I totally agree with the fact that we need to be careful with our actions and realize what impacts they have on our resources. Fisheries are often too free to do what they want and have no limits or consequences for their actions. In the long run if we do not take action soon more species are going to go instinct and our oceans will probably not ever be like they used to be. I believe a solution would be to put more restrictions on fisheries and watch what products are used to avoid too much fertilizer run-off and also do everything in our power to reduce the increase of carbon dioxide in the atmosphere.



I chose to comment on your post because I find this problem to be very scary as well as threatening many of the ocean species we still have today. I totally agree with you, that overfishing needs to be dealt with.However if companies or fisheries continue to overfish without any consequences (ex: monetary fine) then they will continue to do it. Perhaps if we could increase the security of highly dense fish populated ares, it could reduce the amount of unnecessary fish being caught. However I am hopeful, because there are people trying to fix this. According to the article "Senate Commerce, Science and Transportation Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard Hearing: [2]" states that "The South Atlantic Council has identified five areas we propose be addressed in the current reauthorization: 1) Flexibility in ending Overfishing. 2) Flexibility in Rebuilding Overfished Stocks. 3) Define Overfishing on the Basis of the Recruitment Overfishing Level and not MSY. 4) Restrictions on Applying Harvest Moratoriums. 5) Maximum Sustainable Yield (MSY) Specification for Stock Complexes.". In my opinion, this isn't the best plan, however it is a start, and we should consider that a milestone.I hope this issue can e resolved sooner, rather than later, or before its too late.

I decide to comment on this summary because the globe's oceans are threatened by various issues, such as over fishing and pollution you have mentioned and to have more knowledge on the subject and its causes is interesting to me and important to our planet in order for us to keep benefiting from our ocean's resources, which play a major role in human life's nutrition and our ecosystems. In my opinion, over fishing is manageable over time through policies, ententes and aquaculture. The bigger issue is the pollution, which is not as manageable because its impacts are long lasting and it is a struggle to find solutions for it, since it has been stacking up from years behind creating damage. The pollution also plays a role in the fish stocks, so as we already over fish, there are also large amount of fish that are decreasing due to the perturbation of their ecosystem caused by many factors such as the increase of carbon dioxide in the atmosphere mentioned in your summary.
