In fairness the author seems to understand that part, but doesn’t provide a very convincing explanation of why we would need such a repository on the moon for anything short of a civilization-ending catastrophe either:
A: If we have a massive apocalypse on Earth, it’s going to be impossible to access the repository. In my mind, it’s meant for catastrophes like severe hurricanes or some disease that impacts the base of our food chain. The thing that worries me a great deal is the southern oceans. Our oceans are under siege from being warmed and acidified. And if we start to lose the base of our food chain, we are in a lot of trouble. I could imagine some of those organisms needing to be supplemented within 50 to 75 years.
If our food chain is threatened by hurricanes or ocean acidification then why would it make more sense to rebuild from a stockpile buried deep on the lunar surface than from a few dozen stockpiles buried deep in the Earth?
