These preserved marine areas are in danger of disappearing within fifty years, due to increased freight, pollution and overfishing, according to a scientific study.
The oceans are increasingly threatened by human activity. According to a recent scientific study, only 13% of the world's oceans are still considered wild, and these preserved areas could disappear entirely within fifty years, due to the increase in sea freight, pollution and pollution. overfishing. The scientists, led by Kendall Jones of the University of Queensland (Australia), have mapped submarine areas considered intact, and ecosystems "essentially free of human disturbance" .
According to their study, published by the journal Current Biology these wild areas are found largely in the Antarctic and Arctic, as well as near remote Pacific islands. Coastal areas close to human activities are those with the least flourishing marine life.
Marine areas that can be considered intact are increasingly rare as fishing and fishing fleets expand their fields of action to almost all the world's oceans, and sediment runoff buried many coastal areas. Kendall Jones, researcher at the University of Queensland (Australia)
the researcher, "the improvement of maritime transport technologies means that the most remote and wild areas could be threatened in the future". Even the areas "once covered by ice" are no longer protected, "because of climate change" .
In total, only 5% of marine areas that remain wild are in protected areas. The other areas still preserved are therefore all the more vulnerable.
The authors of the study call for strengthening international cooperation to protect the oceans, to better combat overfishing, limit underwater mining and reduce polluting runoff. "We know that these areas are decreasing catastrophically, their protection must become the goal of multilateral environmental agreements, otherwise they will likely disappear within fifty years", alerted James Watson, Australian Wildlife Conservation Society
