‘Our species will disappear’: Earth enters new extinction phase
Humans
have already triggered the start of Earth’s sixth mass extinction,
thereby threatening their own future as a species, a hard-hitting new
study has claimed. The window of opportunity to prevent the worst
diversity disaster since dinosaurs were swept from the planet 65 million
years ago is “rapidly closing,” warn the authors. In the last century
vertebrates have been disappearing at a rate 114 times higher than would
normally be expected without the destructive influence of humans,
according to the scientists, who insist their analysis is “extremely
conservative.”
If it is allowed to continue, life
would take many millions of years to recover, and our species itself
would likely disappear early on.
Dr. Gerardo Ceballos
If
the current pace of extinction is allowed to continue, species loss
will have a significant effect on human populations in as little as
three generations, it is claimed. Once the damage is done, it could take
millions of years for nature to recover, said the researchers. They
pointed out that since 1900, over 400 more vertebrates than expected had
vanished. The lost animals included 69 mammal, 80 bird, 24 reptile, 146
amphibian and 158 fish species. Today, the specter of extinction hung
over 26 percent of all mammalian species and 41 percent of all
amphibians.
There are examples of species all over the
world that are essentially the walking dead. We are sawing off the limb
that we are sitting on.
Professor Paul Ehrlich
