An American researcher warns: The sixth mass extinction on Earth in 2100

A scientist at the Massachusetts Institute of Technology has warned that the planet could face a catastrophic event leading to mass destruction in 2100, saying climate change is pushing our oceans to the brink of collapse..

Professor Daniel Rothman added that at least five mass extinctions have occurred in the past, driven by cosmological and natural phenomena..

Scientists estimate that up to 99.9 percent of all plant and animal life has been destroyed.

The last catastrophe, the third Cretaceous catastrophe, occurred about 66 million years ago when a killer asteroid struck the coast of modern Mexico..

The Cretaceous extinction not only brought an abrupt end to the age of the dinosaurs, but also destroyed 75% of life on Earth at that time..

Many scientists fear that a similar fate awaits us in the future, and the worrying thing is that humans may have a hand in the destruction of the planet..

According to geophysicist Rothman, human activity has the potential to disrupt the global carbon cycle and cause 10,000 years of environmental catastrophe..

In a study published in the journal Science Advances, Rothman said he had studied changes in the carbon cycle over the past 540 million years, including the last five mass extinctions..

Professor Rothman said that based on his research, the Earth could enter an “uneducated area” by 2100, resulting in a catastrophe across the planet that could last up to 10,000 years..

An MIT scientist is concerned about the amount of carbon deposited in the oceans as a result of man-made greenhouse gas emissions..

Due to the high carbon content of the oceans, it makes the water very acidic and cannot be treated to many animal species..

According to Professor Rothman, at least four of the last five mass catastrophes were associated with increased rates of carbon dioxide conversion..

He believes humans are putting more carbon into the atmosphere, faster and in shorter periods of time than past geological events..

Professor Rothman estimates that the amount of carbon in the ocean is 300 gigatons per century..

Unfortunately, some estimates suggest that by 2100 the Earth will be on track to add 500 gigatons..

“Mass destruction is a kind of chain reaction that causes the global ecosystem to collapse,” Rothman said.. “

He added: “What we see today is very dangerous; however, I do not know how important it is for the global ecosystem to move us to the point of creating a global catastrophe.. “
