IT’S OKAY TO BE SMART

Whose Air do we Share?

  • Aired: 04/09/2013

  • Rating: NR
Earth's atmosphere is big, but not as big as many people think. All the air that keeps us alive is just a thin candy shell around our planet. In this episode, echoing the words of John F. Kennedy, I'll show you the science of how we all share the same air. So let's be careful about what we're putting in it.
