END OF THE WORLD
If the world was going to end (for reals), how do you think it would go about ending?
End of humanity or end of the planet?\
I'll start with the easier alternative. if the end of humanity were to come about, it'd probably be due either all of us killing one another after the oil runs out, or a war breaking out that spares no one.
If the entire planet were to be destroyed, I think it'd have to be way more severe than anything humans could do and even more severe than anything the planet could do to itself. I believe the closest thing we have to the end of our planet is the sun dying.
I don't see that as being as likely. We have a pretty resilient atmosphere that has protected us from space debris for a while now. No reason to believe it'll be penetrated any time soon. Though now that it's brought to my attention, the likelihood of humans destroying the atmosphere enough that debris could knock us out of orbit does seem more likely.
Sorry, it started out as one thought, then transformed into another, I just decided to keep both.
