We do not say anything new warning that the world’s oceans are at risk of entering a phase of extinction of marine species. A fact that could be equated with the hecatomb that 55 million years ago caused the disappearance of half of the deep- sea fish , would be a disaster for the biodiversity of our planet .
The scientific explanation
Several scientists assure that there is solid evidence that the oceans are dying and that the first steps towards an extinction of global importance unprecedented in the history of mankind could have already been taken, whose main trigger for this catastrophic event has been the increase of polluting gas emissions such as CO2.
Carbon uptake in ocean waters appears to have been increasing in recent older years, something that could lead to a mass extinction of marine species and the bleaching of corals in the tropics around the world. On the other hand, overexploitation, pollution, warming waters, their acidification and lack of oxygen, are some of the many factors that have negatively affected the biodiversity of the oceans.
Nor should we forget the rise in sea level, the melting of the Antarctic polar caps and the release of methane from the seabed, all of which greatly affect the redistribution and abundance of marine species. Changes in currents and water temperatures also disturb the feeding of fish, favoring the proliferation of plankton and organisms of little nutritional value. From here we want to urge an immediate stop to carbon dioxide emissions by the industry, to bet on renewable energies once and for all, to control overfishing, to improve protected areas, stop marine pollution, monitor submarine gas and oil pipelines, water discharges and adopt measures to prevent major natural disasters.
