Get this:

The European Space Agency's chief scientist has said that there should be a Noah's Ark on the Moon, in case the Earth is destroyed by an asteroid or nuclear holocaust.

...

"If there were a catastrophic collision on Earth or a nuclear war you could place some samples of Earth's biosphere, including humans, [on the Moon]," he said.

"You could repopulate the Earth afterwards like a Noah's Ark," he said.

Now, if the earth were decimated by a nuclear holocaust, it would essentially destroy the ecosystem and make conditions unlivable for perhaps thousands of years, right? Am I missing something?

Why don't we try to focus a bit more on making sure nobody ever uses the damned things?
