The planet is in danger of dying in the oceans to mass extinction

At that time, a meteorite and volcanoes destroyed life on Earth, but now people can be held responsible.

In the absence of a drastic and rapid response to climate change, the greenhouse gases that heat the oceans and consume their oxygen, as well as the destruction of “habitats” and the pollution of coastal areas, will wipe out the sea.

An article signed by researchers at the Universities of Washington and Princeton recalled that emissions of large anthropogenic greenhouse gases are radically changing the country’s climate system and threatening many species.

The study warned that while the impact of climate on biodiversity is difficult to detect, especially for ocean life, given the fossil history that illustrates past massive extinctions caused by radical environmental change.the future of ocean life as we know it is uncertain in the face of climate change;“.

Study authors Justin Penn and Curtis Deutsch assess the risks associated with the extinction of ocean species in different warming scenarios. A global ecophysiological model that emphasizes the physiological boundaries of a species according to sea temperature and oxygen predictions.

Its conclusion was that If global warming continues unabated, it is likely that the marine ecosystems of the entire planet will experience massive extinctions similar in size and severity to the end of the Permian season 250 million years ago, known as high mortality, which caused the Earth to disappear. more than two-thirds of marine animals.

After the study, the tropical oceans are most likely to lose the most species due to climate change, although many of them will move to higher latitudes and more favorable survival conditions.

On the contrary, polar species must become extinct because their “habitat” is completely extinct.

one more warning

In another article published alongside the quoted article, researchers Malin Pinsky and Alexa Fredston of Rutgers University in the state of New Jersey confirmed that “climate change is driving species away from the ends of the earth“.

But they pointed out that reducing greenhouse gas emissions can reduce the risk of extinction by up to 70 percent.

In doing so, they reaffirmed that preventing large-scale biodiversity loss and the sixth mass extinction is now a “global priority.”

Whether humanity faces a worst-case scenario or a worst-case scenario depends on decisions made by society, not only on climate change, but also on the destruction of “habitats”, overfishing and coastal pollution.“, warned.

Pinsky and Fredston argued in this way that “with a coordinated focus that addresses multiple threats, living in the ocean as we know it has a better chance of surviving in this century and beyond.”
