The Causes And Impacts Of Overexploitation - 1855 Words

If fishing continues at the same rate, using todays destructive practices, the oceans could become fishless by 2048 (Branch, 2013). Understanding and analyzing the causes and impacts of overexploitation in oceans, can offer insight into possible solutions to remediate current and future effected environments. Today, (see Figure 1) 53% of the worlds fisheries are fully exploited and 32% are overexploited, depleted, or recovering from depletion (FAO, 2010). The overexploitation of the oceans is directly linked to overfishing. Overfishing can be defined as â€Å"fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest† (Hilborn and Hilborn, 2012). Post industrial revolution there was an increase in global fishing and consequently an increase in catches. The large scale industrialization of the fishing sector inevitably led to over-fishing, causing the collapse of many fish stocks (Pauly, 2002). Due to unsustainable fishing practices an increase in overfished and fully fished stocks can be observed over time (see Figure 1). The fishing industry has had to adapt in recent times to maintain the quantity of fish being caught, one way they have achieved this is to start fishing at greater depths, today more fish are being caught deeper than ever before (see Figure 2). Deep sea fishing is mostly consider ed unsustainable, (Norse, 2012) as itShow MoreRelatedImpact Of Overfishing On Marine Ecosystems And Human Culture1724 Words   |  7 PagesIntroduction Overfishing occurs when fish are being caught faster than they can reproduce and replace themselves (Lee and Safina, 1995, pg.5). It greatly affects biodiversity of marine ecosystems and human culture. Impacts of Overfishing Overfishing can impact marine ecosystems and communities that rely heavily on marine mammals. Large reductions in population sizes of marketable fish species caught yearly may significantly create economic stress within fishing communities, especially if theyRead MoreHabitat Destruction1612 Words   |  7 Pagesmany things. These include: The introduction of alien (exotic) and domesticated species Pest and Predator control The collection of animals for pets and research Pollution Ecological factors Loss of keystone species Overexploitation Disease Limited distribution Many of these causes could be prevented fairly easily. If people today would just follow some simple rules, none of these would be as big as they are now.

Overfishing can occur in water bodies of any sizes, such as ponds, rivers, lakes or oceans, and can result in depletion of certain resources. By deplete resources is meant using up or consuming supplies. Coastal management is defense against flooding and erosion, and techniques that stop erosion to claim lands. Both hard engineering and soft engineering are types of coastal management strategies.

NOAA states in â€Å"What is coral bleaching?†, bleaching is the by-product of corals getting too warm; when corals get too warm they expel the algae (zooxanthellae) living in their tissues, which causes them to turn completely white. Today, the remaining coral reefs are being stressed by the human inhabitants who exist upon the land masses from which these reefs neighbor; which, in turn, has caused these remaining reefs to approach extinction. MoreoverRead MoreHow Humans Have Affedted the Antartic Food Web1041 Words   |  5 Pagescertainly the most pristine environment left on the earth. Unfortunately this is no longer the case because of multiple human activities that have led to environmental issues and concerns such as pollution, ozone layer thinning, global warming etc. Human impact is a serious threat to ecosystem and food chain of Antarctica. In the last few decades, various marine species of Antarctic ecosystem have been brought close to extinction because of human activities in various forms such as pollution from sewageRead MoreThe Environment Of Marine Life833 Words   |  4 Pages$100 million worth of fisheries are relying on coral reefs [4]. However, anthropogenic activities like pollution, overfishing and destructive fishing practices like blast fishing are posing a threat to the existence of coral reefs. While overexploitation is one cause, pollutants like chemicals, insecticides and debris when mixed with the saline water increases the nutrient levels thereby promoting growth of algae that destructs the corals reefs.

From a long-term perspective, because waste ahead of use and consumption of water resources and funds should not be used, will cause the water-deficient areas in the future as new water resources to pay a higher price.
