'Last Days on Earth'

— -- How smart are we as a civilization?

Smart enough to control our destiny and avoid the cataclysms that may end life as we know it?

For thousands of years, different religions have warned Earth about Armageddon and the final days.

We are now living in an age where scientists are adding their voices and their evidence in support of end-of-the-world possibilities.

"Last Days on Earth" is a program that could change the way you see your world and yourself.

The world's top scientists, including Stephen Hawking, considered the foremost living theoretical physicist, describe seven riveting scenarios detailing the deadliest threats to humanity.

Some can destroy the planet, others have the ability to render us extinct, and all have the power to destroy civilization.

How likely are they to occur, and what exactly would happen if they did, and could we survive?

"Last Days on Earth" goes beyond science fiction to science fact.

Using state-of-the-art visual effects, it will take viewers on a journey that is both breathtaking and terrifying, from the outer reaches of the universe to the inner world of DNA, with an around-the-globe tour in between.

"Of all the generations of humans that have walked the surface of the Earth -- for 100,000 years, going back when we first left Africa -- the generation now alive is the most important," said Michio Kaku, professor of theoretical physics at City University of New York.

"The generation now alive, the generation that you see, looking around you, for the first time in history, is the generation that controls the destiny of the planet itself."

"Last Days on Earth" is anchored by Elizabeth Vargas. Rudy Bednar is the executive producer. Michael Bicks is the senior producer.
