Can we Re-Build Civilisation after Collapse.

[Scythe13]

The only caveat I would make is that even if political and social units get smaller, they may have very little 'spunk' to keep them going.

Even with that being the case, human beings have colonised and small units will become big groups, and cities will start again.

I don't think we'll go back to identical living, but different. We will eventually be more advanced, e.g. replace oil for fuel with hydrogen cells and things like that.
