Two of the podcasts I listen to just covered a similar topic: How societies handle disaster, why we usually are unprepared, and how we could do better. Both are above the usual crop and thus highly recommended!

Sean Carroll talks to Niall Ferguson about a large variety of things. Too many bits of wisdom to even try picking a quote from the transcript.

Sam Harris brings on Rob Reid who delivers a riveting monologue, broken up by discussion, that vividly outlines why synthetic biology can pose a real threat, and what can be done to put countermeasures into place early enough. Four hours well spent!
