Seriously, i very much doubt it, although it depends on what you define as the world ending.
I've experienced bananas in pajamas. (sorry couldn't resist it).
I once forgot about some bread i had, when i found it it was green, and very powdery. :S
Probably, but it's more fun to do it yourself, you get the satisfaction of going.
"HAHAHA i see you ad, but not for much longer, welcome to obscurity!!!"
Source isn't really built for this type of dynamic terrain distruction, for a number of reasons.

No, that wouldn't work. If you look at a mirror side on, you don't see yourself!
You could get a camera that looks in the correct direction depending on the player's position and output that though, i think.
You should have said this:
"Look, i'm sorry you are angry that your only talent is being good at computer games, but there's no need to take it out on me."
lol, i'm only joking.
Those i mentioned could be thought of as small versions of common potatoes, and tomatoes, so you could think of them as 'children'.
