Summoning the “Ingenuity and Courage”

The question posed at left by astrophysicist Neil deGrasse Tyson is a good one: Can we summon the ingenuity and courage required to save us from environmental collapse?

FWIW, lots of smart people say no.  Kurt Vonnegut, for example, predicted shortly before his death that this will be the first civilization in human history that didn’t save itself because it wasn’t cost-effective.
