Overfishing and Killing Marine Predators

by ZFavreau on November 6, 2015 - 7:06pm

The article, published on the Florida International University website, summarises a study about overfishing and killing marine predators. This article states that while human beings continue overfishing, they are not only affecting their preys, but also indirectly impacting other parts of the ecosystem. Moreover, by affecting the behavior, the distribution as well as the numbers of predators, human beings can also influence the prey’s chances of being killed and the way it responds to threats. Mike Heithaus, a Florida International University (FIU) scientist and the dean of the FIU College of Arts and Sciences, states that “This study shows there are many more consequences than are generally recognized. These really need to be considered in ecosystem management and conservation efforts”. Up to now, every scientist knew the direct effects of overfishing and killing marine predators. The current study shows the indirect effects. Furthermore, the research paper connects the dots of what is unknown and what is known about how we indirectly affect evolutionary processes, ecological processes and animal behavior.


Personally, I think that this new study clearly shows how we, human beings, are affecting the Earth and its different ecosystems. Additionally, the whole marine ecosystem is extremely important for the Earth and thus, should be one of our main concerns. In order to solve this issue, I think that we should carefully choose our seafood. We should make sure that the seafood that we eat and buy is sustainable. To conclude, I also think that we should make further investigations about the effects of killing marine predators and overfishing in order to build a framework for informing management and conservation decisions.

I totally agree with the solution you brought and I understand that it is important to protect our animals to conserve our ecosystem but if you look on the other side , one of the leading cause of death in marine mammals is pollution. Many pollutants and heavy metals are releasing in the oceans and all these pollutants are dangerous to our health and can lead to numerous incurable diseases (http://www.ncbi.nlm.nih.gov/pubmed/21182713). So, I think that the solution is not to stop fishing or to choose our seafood but our priority should be to pay attention to what we throw away. finally, even if we continue to fish them, they will be able to reproduce themselves because they will be healty.

The content of your text is very interesting and relevant but I am concerned about the reliability of your source. The text in which you based your information appears to have been written on a blog. For the next time, I would suggest you to use a governmental site. This way, we can be sure that the content of your text is reliable. According to me, this text (http://www.ncbi.nlm.nih.gov/pubmed/21182713) would be more appropriate because we can easily rely on it and it is a governmental site.
