It is not an escape of any kind. The society is just akin to what you called Earth neighborhood. I live in The Netherlands, so I am part of the society of The Netherlands but also of Benelux and EU and Europe and Earth and what not. It has nothing to do with ‘god help us’, religion has nothing to do with this, as its not a belief system, its a social contract, akin to how a democracy works (but beyond that since climate change affects us all).
Nuclear waste is not forever that is what certain eco terrorists want us to believe, it has a certain half-time, and besides that it does not matter if its stored securely. Yes, the fact we need to store nuclear waste sucks, but its better than coal.
Coal’s dump isn’t short-term, the Co2 effects are there, which nuclear fission and fusion do not have. We have climate change problem right now, so it makes sense to get rid of all the coal stuff and replace it with nuclear (since there’s more demand that sustainable can yield).
In short, if the choice is between coal and nuclear, the choice is simple: nuclear, ASAP (cause it takes time to implement). Every day we wait is one day too much on coal.
