What is the Sixth Mass Extinction?

0

The Sixth Mass Extinction, also known as the Sixth Extinction or the Holocene extinction event, is an ongoing extinction event perpetrated by human beings. It began about 50,000 years ago, when modern man first left Africa. Since then, it seems to have been nothing but havoc. At least 20,000 species have gone extinct at the hands of humans, and possibly far more. Terrestrial species have had it the worst, as that is where human influence is strongest.

At least 20,000 species have gone extinct at the hands of humans, and possibly far more. Terrestrial species have had it the worst, as that is where human influence is strongest. First, from about 50,000 to 20,000 years ago, dozens of species of megafauna — large animals such as mammoths, saber-toothed tigers, the Dire Wolf, cave bears, and many others — went extinct shortly after humans started moving in on their territory. These are called the Pleistocene megafaunal extinctions, and represent the first phase of the Sixth Mass Extinction. Climate change is sometimes advanced as a cause for their extinctions, but this argument bears little weight, as the animals in question survived numerous glacial and intergla
