Caldwell believes people are fundamentally good, but we are reaching a tipping point.

Transcript:Well I think to go back to my earlier remark that, you know, you’re ultimately . . . you either believe we’re fundamentally good or you don’t, I am fundamentally optimistic, not pessimistic; but I think we’re at a tipping point here now. And I think that . . . I mean we now have possessed for decades the potential to annihilate ourselves hundreds of times over. And just as we possess those nuclear and chemical weapons that could annihilate us hundreds of times over, we are annihilating ourselves daily by virtue of how we live with respect to the climate that’s collapsing around us. So I, you know . . . I just . . . I hope we’re at the moment. And it seems to me we may be where we going to have to do a radical rethink of how we’re living. Because we cannot continue to consume in the way that we consume. We cannot continue to communicate and to misunderstand in the way that we do. And the stakes are simply too high in terms of how lethal our activity is and has been.
