Please, Save the Specie

New York City inspectors found what they believe to be a nuclear fallout shelter from the Cold War era. We hear about this sort of things quite frequently, a bomb shelters here, a room full of supply there. The thing I never quite understand is that why these sorts of things have to be found? They were supposed to be used when the end of the world came, when they were to support human lives to ensure the survival of the specie. What we learn now is no one really knew where these things were. If anything had happened, it would certainly puzzle aliens who visit the deserted earth in a few millennia later and found unused survival material with no survivor. That would certainly create a great mystery that would be broadcasted all over the universe. Some may speculate that there must had been a conspiracy to hoard and hide all the emergency supplies to ensure the extinction of the specie. It is fortunate that, for the time being at least, that danger has passed. But then, maybe a few thousand years later aliens will find millions of doses of Tamiflu in corporate warehouse on an empty plant. Our great leaders are such excellent planners of disasters.
