Doomsday Vault

An underground vault will start operation today on an island near Artic Ocean. The vault will house millions of seeds from the every corner of the Earth. The idea is to provide the 'new world' with a lease of life should doomsday arrive.

One question (ok, several actually) popped up the moment I saw the article. What are the chances of the vault surviving when doomsday come? Why stop only at one vault? It's a typical case of all eggs in a basket. Why not install a vault in the moon instead? There is a good chance that the aliens would neglect the moon when the invasion comes. What makes the scientist think that the conditions would be suitable for germination after doomsday? Wouldn't that be thinkering around with nature if new species have to compete with those stored in the vault?

Whatever the answers may be, the New York Philharmonic Orchestra is desperately trying to do its bit in delaying doomsday by charming Kim into deactivating all his nukes.
