The beginnings of a Mass Extinction

Officially we are in the beginnings of the sixth mass extinction that could threaten humanity’s existence.   Take a look at the important video…

Scientists warn that the sixth mass extinction has begun and this time we’re to blame!

The five previous extinctions caused by natural disasters, but this is man-made.

Species are disappearing more than 100 times faster than normal rate and it could take Earth millions of years to recover.

Mass Extinctions

There is no longer any doubt: We are entering a mass extinction that threatens humanity’s existence.

That is the bad news at the center of a new study by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment. Ehrlich and his co-authors call for fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing.

Mass extinctions are periods in Earth’s history when abnormally large numbers of species die out simultaneously or within a limited time frame. The most severe occurred at the end of the Permian period when 96% of all species perished.

The average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way. Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing.
