Re: reducing energy consumption
If you're going to give up comfort, why bother to live at all? What really is the point? Why bother to breed, for that matter - all you'd be doing is condemning another soul to a life of misery, a grossly selfish and wicked act just to satiate your animal instincts.
Or we could ignore retards, spark up a few nuclear plants, and everyone could live in luxury.
I know which sounds more tempting to me.
