It's a mystery on a global scale: five times in Earth's past, life has been nearly extinguished, the vast majority of plants and animals annihilated in a geologic instant. What triggered these dramatic events? And what might they tell us about the fate of our world? MASS EXTINCTION: LIFE AT THE BRINK joins scientists around the globe as they unravel the mysteries of two of the most dramatic mass extinction.

Mass Extinction: Life at the Brink joins scientists around the globe as they unravel the mysteries of two of the most dramatic mass extinctions - the "K/T Extinction" that wiped out the dinosaurs, and "The Great Dying," which obliterated nearly 90% of all Earth's species. At first glance, these two extinctions couldn't look more different. A six-mile-wide asteroid spelled near-instant doom for the dinosaurs. And as new research covered in the film reveals, massive volcanic eruptions altered the chemistry of the atmosphere and ocean to trigger "The Great Dying." As different as they seem, these two extinctions share uncanny similarities and a message for today. Could the impact of human beings be just as devastating to the planet as a massive asteroid strike or volcanic eruptions?

VIDEO USAGE RIGHTS

Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.
