17 minutes

Greetings

     Got this video from Reuben  (Thanks!).  If a Tedx talk by Dave Roberst, of Grist   I've been reading his stuff for a while, and have been very impressed.with his ability to take complicated info and make sense of it.

     Here he puts a lot of info together in a way that is quite compelling.  

A good video to go viral.

     So if you've got 17 minutes to spare, I think it  would be worth while. .
