Oceans: it is an alarm of extinction for the animal species that inhabit them

    Oceans: it is an alarm of extinction for the animal species that inhabit them

    The report that takes the pulse of oceans around the world was released yesterday. And the news is not good at all. There is a risk of extinction of the life forms that inhabit our seas

    The animal species that inhabit the oceans are at great risk. This is what emerges from the report "International Earth System expert workshop on ocean impacts and stresses" released yesterday at the seminar of"himself with the International Union for Conservation of Nature (IUCN) and the World Commission for Protected Areas (Cmap).




    An international group formed by 27 scientists di 18 organizations from 6 countries. The document, which summarizes the results of another seminar held last April at theOxford University, has highlighted the truly disconcerting state of the seas of our planet. In particular, the combined effects of pollution, acidification, heating, overfishing e lack of oxygen.

    The contemporary association of these factors causes significant consequences for the health of the waters and its inhabitants. In particular, the lack of oxygen, heating and acidification, according to experts, were also present in each of the previous phases of mass extinction recorded in the history of our planet.

    Processing beyond 50 documents who have examined the state of health of our oceans, scholars have noted an increase in the levels of carbon absorbed by the seas, "much higher than at the time of the last mass extinction of marine species, about 55 million years ago, when some groups of animals suffered 50% of losses ". In addition, a single mass bleaching event, which took place in 1998, killed 16% of all tropical coral reefs in the world.

    This is the comment of Alex Rogers, Scientific Director of the International Oceans Program (Ipso): “The results are shocking. As we have considered, the cumulative effect of what humans do to the oceans is far worse than what has been achieved before. This is a very serious and challenging situation to deal with. We are trying to evaluate the consequences for humanity and for the impact that extinction may have in our lives, and worse still, in those of our children and for future generations ”.


    Intensive fishing is also on the dock, which for its part has produced a 90% reduction in some species, together with the dumping into the sea of ​​agricultural and industrial products that are literally devastating the natural habitat.


    Dan Laffoley, chairman of the World Commission on Protected Areas (IUCN) and co-author of the report, said: “The world's leading ocean experts are amazed at the speed and scale of the changes we are witnessing. The challenges for the future of the oceans are enormous, but unlike previous generations, today we know what will happen. The time to protect the blue heart of our planet is today ”.

    And immediately after the alarm and shocking data on the risk of extinction of animal species in the oceans, the environmental association Marevivo calls for a world summit, "a G20 for the sea ", with the aim of "designing a global strategy for the protection of the sea and identifying protection measures that can guarantee the oceans to continue to play their role in producing 80% of oxygen and absorbing 30% of carbon dioxide".

    "The sea, with its multitude of plant and animal living beings, from phytoplankton to large whales, from Posidonia meadows to sharks, must be the center of attention - explains the president of Marevivo, Rosalba Giugni - And it cannot be forgotten: if the sea dies, there will be no life even for man on the planet ".



    In short, borrow the words of the association "the sea" boils "under the weight of global warming," suffocates "by failing to function as the lung of the planet and" drowns "due to pollution". Do we want to stay and watch?
