What will cause the 6th mass extinction?
Unlike previous mass extinctions, the sixth extinction is due to human actions. Some scientists consider the sixth extinction to have begun with early hominids during the Pleistocene. They are blamed for over-killing big mammals such as mammoths.
Will humans survive the next mass extinction?
We’re so uniquely adaptable, we might even survive a mass extinction event. Given a decade of warning before an asteroid strike, humans could probably stockpile enough food to survive years of cold and darkness, saving much or most of the population.
