Overfishing and Killing Marine Predators

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.
