How Many Protected Areas benefit the ecosystem
MPAs restrict human activities including scuba diving, fishing, and boat presence in the area to allow for restoration of a particular ecosystem community in dire need of help. Today, only 3.7% of the world’s oceans are protected under law, and many of these protected areas are poorly managed, while only 2.0% of the ocean is strongly protected in no-take marine reserves. Many countries are now trying to reach a goal of having 10% of their oceans being protected by the year 2020.
Marine protected areas have many proven benefits to both the ecosystem and to the surrounding communities. MPAs act to maintain biodiversity for both endangered and commercial species, as the removal of human presence allows for many different species to thrive without anthropogenic influence. They also protect certain habitats from being damaged from destructive fishing gear such as dredging and trawling, and allow for these habitats to recover from previous destructive fishing practices as well.
