TED: Caitria and Morgan O’Neill: How to step up in the face of disaster - Caitria O'Neill / Morgan O'Neill (2012)

Summary: After a natural disaster strikes, there’s only a tiny window of opportunity to rally effective recovery efforts before the world turns their attention elsewhere. Who should be in charge? When a freak tornado hit their hometown, sisters Caitria and Morgan O’Neill -- just 20 and 24 at the time -- took the reins and are now teaching others how to do the same. (Filmed at TEDxBoston.)
