Extinction is a natural process, and five times in the dim reaches of Earth’s long history it has happened on a huge scale. Now, due to human activities, another mass extinction has been set in motion—and it is unfolding at an unprecedented speed. This program, hosted by David Attenborough, investigates the devastating effects of humankind’s overpopulation and overconsumption in an attempt to understand how the crisis may yet be averted. The research of conservation biologist Tom Lovejoy, marine biologist Sylvia Earle, climatologist Stephen Schneider, and biologists Jared Diamond, Edward Wilson, John Lawton, and Sir Robert May is featured. A BBC Production. (50 minutes)
