This stunningly beautiful video shows how when push comes to shove and the world goes boom (or for the optimists when we build a big ol' rocket ship and get the hell out of dodge) Kew Gardens and the Millenium Seed Bank people are the ones that we will be relying on.

Having just recently re-watched The Road ( a movie I still feel somewhat ambiguous about, the introspectiveness of the concept works far better in book format), I am immensely relieved that this is a thing. I think all countries should mutually agree to if at all possible avoid blowing it up, cuz ya know, that would be bad. Also, we've gotta make sure Wolfgang survives (everyone needs a Wolfgang). He looks like a guy who can be counted on come the end times.
If you've got a bit more time on your hands, here's a longer vid about this amazing place.
