T. Boone Pickens: Let's transform energy -- with natural gas

The US consumes 25% of the world's oil -- but as energy tycoon T. Boone Pickens points out onstage, the country has no energy policy to prepare for the inevitable.

If an asteroid were headed for Earth, we'd all band together and figure out how to stop it, just like in the movies, right?

Jonathan Haidt shows us a few of the very real asteroids headed our way -- s...
