No animal or species on earth is permanent. One day they will disappear. This is the law of nature. But there have been mass extinctions at some point in Earth's history. This is called 'Mass Extinction'.
Simply put, if a natural disaster or an asteroid hits the earth and causes the extinction of many species, it is called 'mass extinction'.
There have been five such catastrophes on Earth so far that have consumed the entire fauna. Most land species became extinct. The most significant mass extinction occurred 66 million years ago.
Dinosaur species were wiped out from the earth by an asteroid impact. Research is still going on in different countries about the extinction of this species that walks the earth. But the current scientists say, that is not the end, the world is going through another i.e. the sixth mass extinction period.
And the cause is not an asteroid but human civilization itself. By destroying the environment and nature, man himself is making this habitable world uninhabitable.
A new study suggests that the next mass extinction will occur as a result of climate change and environmental pollution. The massive use of fossil fuels will accelerate this mass extinction.
A group of researchers from the University of Bristol in the UK conducted the study. According to a recently published research report, multiple computer simulations suggest that the Earth will face a mass extinction that will wipe out all mammals.
According to the research report on when this mass extinction will start, within the next 25 million years, humans will disappear from the earth. The report says that even if people completely stop using fossil fuels now, it will happen in that time.
A section of scientists say that greenhouse gases, especially carbon, are being emitted for some reasons such as destruction of the environment and nature, deforestation and extensive use of fossil fuels. As a result of which the earth is becoming warmer or hotter. Which is causing climate change.
If people do not stop destroying the environment and nature and using fossil fuels, this global warming will continue to increase. That is, the temperature of the atmosphere will increase greatly.
Researchers at the University of Bristol say that within the next 250 million years, any living creature on Earth will have to deal with temperatures ranging from 104 degrees Fahrenheit to 158 degrees Fahrenheit, or 40 degrees Celsius to 70 degrees Celsius.
It is clear from the research reports that temperature of 40 degree Celsius to 70 degree Celsius will not be bearable for humans and other animals. As a result these animals will die in mass. Through which mass extinction will begin.
The new study was led by senior research fellow at the University of Bristol's School of Geographical Sciences. Alexander Farnsworth. This researcher said, 'The view of the distant future seems very dark and uncertain.'
According to Farnsworth, carbon levels could be twice as high as they are now. Humans, along with many other species, cannot adapt to those demands. As a result they will disappear.
Earlier, a study published in November last year said that various species of animals are walking the path of mass extinction at a speed 35 times faster than their normal speed. Many species are lost during each extinction; On the other hand, some species persist. If people think that only they will survive this cycle of loss, that idea would be wrong.
Gerardo Ceballos, co-author of the study, said that this void lost from Earth must be filled. But it is difficult to say who will survive and who will be lost among nature's biodiversity.
A separate study published in the international biological research journal 'Biological Reviews' around last year says that this process of terrible destruction has already begun on earth. Six and a half million years ago, after the Cretaceous period, the sixth stage of mass extinction of life has started at least 700 years ago, since the 1500s.
The study also said that seven and a half to 13 percent of the world's two million known animals and plants have already become extinct or lost forever. How the dinosaurs got lost.
