I’m reminded a bit of the plant genome library or whatever it’s called. There’s a big vault where they have sufficient samples of as many plant species as possible, so if we have some cataclysm they can restore the plants in a properly species diverse way, and from that you can restore agriculture and from that you can restore civilisation, or at least that’s the theory. I think it’s in Greenland maybe? Somewhere ruddy cold generally anyway.
Ah, The Global Seed Vault in Svalbard
