I know what it is..the libs want us to suffer WITH them and go back to that wonderful time when we embraced Mother Gaia and lived on trees and rocks without “harmful” technology.
It has survived enormous impacts, the vagaries of plate tectonics, massive volcanic eruptions, so a few shuttle launches--or car air conditioners won't make much difference in the long run.
Frankly, I see the entire panic series as an excuse to keep people here on the planet, in the dark, and living in mud huts, with the exception of the 'enlightened few' who would be our overlords.
Imagine the horror those same would-be overlords feel at the thought of people living somewhere without so much as a homeowner's association to browbeat them.
As for the Earth, yes, we can render some or even all of the planet surface unsuitable for human habitation for a while if we really, really try, but it will recover--with or without us, despite any concerted effort we made to destroy it, and we simply aren't working hard enough toward the ends of crapping in our nest. Even at its unfettered polluting heyday, industry and world war combined couldn't destroy the planet.
Megatons of atmospheric nuclear tests didn't send us spinning off into some cosmic rift.
Heck, we couldn't even find the 'Andromeda Strain' out there on the Moon.
In the meantime, we would do well to not keep all our eggs in one basket. Perhaps we could learn something to settle our species-centric narcissism once and for all.
