Sixth mass extinction coming ‘soon’: ‘Species disappearing at alarming rateâ€™, humans to become extinct
There is no denying the fact that it is a scary thought. A latest study says that the earth might be staring at a mass extinction. The world has already suffered five mass extinctions, and if God forbids, it happens again, it will be the sixth mass extinction on the earth.
The study says that the mass extinction may cause the destruction of the entire living beings on the earth, or at least the compete destruction of the human race from the face of the earth.
The latest study that has been published in the journal Science Advances, actually proves that going by even conservative estimates, species are disappearing up to about 100 times faster than the normal rate. And according to them this all indicates the fast approaching mass extinction of the world.
According to studies carried out, the last of five mass extinctions actually happened some 66 million years ago when dinosaurs were exterminated from the face of the earth. “(The study) shows without any significant doubt that we are now entering the sixth great mass extinction event,” said Paul Ehrlich, senior fellow at the Stanford Woods Institute for the Environment. The researchers have warned that humans could be among the species lost as a result of the current mass extinction event.
Lead author of the path-breaking study Gerardo Ceballos from the Universidad Autonoma de Mexico says, â€œIf it is allowed to continue, life would take many millions of years to recover, and our species itself would likely disappear early onâ€. There is general agreement among scientists that extinction rates have reached unparalleled levels since the dinosaurs died out 66 million years ago. However, some have challenged the theory, believing earlier estimates rested on assumptions that overestimated the crisis.
The study analyzed many features to reach the conclusion. Using fossil records and extinction counts from a range of records, the researchers compared a highly conservative estimate of current extinctions with a normal “background” rate estimate twice as high as those widely used in previous analyses. This way, they brought the two estimates – current extinction rate and average background or going-on-all-the-time extinction rate – as close to each other as possible.
While writing in the research paper, scientists said, â€œWe emphasise that our calculations very likely underestimate the severity of the extinction crisis, because our aim was to place a realistic lower bound on humanity’s impact on biodiversityâ€. Now, the specter of extinction hangs over about 41% of all amphibian species and 26% of all mammals, according to the International Union for Conservation of Nature, which maintains an authoritative list of threatened and extinct species. “There are examples of species all over the world that are essentially the walking dead,” Ehrlich said
