Marine resources are so much important for the humans as “97 % of all the water on the Earth is in the oceans” (Yang) and because “71% of Earth’s surface” (Woods Hole Oceanographic) is covered by oceans. Stabilizing climate temperatures, exchanging of climate gases, and increasing biodiversity are parts of benefits that the ocean yields us. Similarly, ocean produces half of the oxygen that the humans breathe and offers a great environmental condition that keeps organisms alive and growing. As Langreth has rightly pointed out ocean offers shelter to an estimated “five million species, most of which have not yet been classified” (Langreth). However, man’s indiscriminate actions such as dumping waste materials, oils, overfishing, and noise pollutions pose great threat to the marine life in oceans. It is imperative that man protects and conserves marine life through such radical measures as the marine protected areas. It can thus be seen that implementation of marine protected areas can offer the best solution for the uncontrolled overfishing and overexploitation of marine life.
In 2010 a decade-long international survey of ocean life showed that overfishing caused the disappearance of 90% of the big fishes from the oceans including the largest animal on the planet- the blue whale. More than one million species are living in ocean and they are primarily the victims of overfishing. Certain species such as bluefin tuna have already been destroyed or disappeared from the ocean. While overfishing has led to the disappearance of tens of thousands of bluefin tuna across the seas of Northern Europe in the 1930s and 1940s it has contributed to the vanishing of Halibut from the North Atlantic during the 19th century (Overfished and under-protected: Oceans on the brink of catastrophic collapse). Similarly, trawling towards is one of the methods for fishing and it is really harmful to the ocean. Bottom-trawling which involves
