Hank takes us on a trip through time to revisit the 5 major mass extinction events that have impacted species over the Earth's history, and leaves us with some thoughts about what could possibly be the sixth event - the one caused by human activities. (SciShow)
An international group of scientists has concluded that the Earth and its creatures are dangerously close to a mass extinction event that can be compared to the one that annihilated the dinosaurs 65 million years ago.
A landmark study released by researchers working for a project at Duke University in North Carolina have found that extinction rates are currently 1000 times higher than normal "background rate" due to deforestation, global climate change and the depletion of ocean fisheries.
Researchers said the Earth is on the brink of a "mass extinction event" or a widespread and rapid decrease in the amount of life on earth. They said this would be the sixth great extinction in the history of the Earth.
More chillingly, they said this mass extinction event is already underway, and that humans could be the underlying cause. The scale of the forthcoming mass extinction event could rival the one that wiped-out the dinosaurs 65 million years ago, including a third to a half of all animal species on the planet.
