Seed Vault: The Norwegians are mad

The Norwegians plan to build a vault to hold all varieties of seeds. So, if there's a global catastrophe there'll be seeds left for future generations to plant. At first blush, this may seem like a good idea. But if there's a global catastrophe, who will be here to plant the seeds? What's more, given the catastrophe they envision: nuclear war, severe global warming (whatever that means) how will the seeds even grow?

If there's a catatrophe that would require such seed storage you can bet few humans will be able to use those seeds.
