Is There Something at the Bottom of This Amazing Civilization That We've Managed to Construct?

The idea is to see if there's something at the bottom of this amazing civilization that we've managed to construct, that i think is peril for a variety of reasons. And maybe if we understand it a bit, little bit better, we won't be so prone just to throw the damned thing away - which i think would be a big mistake.
