This came up in a private conversation and I realized I had no idea, but am interested in the answer.
Assuming it does matter, how does the Earth's continents being divided into separate continents help Mankind survive on the world---as opposed to if the world was still just a vast continent with an enormous single continent?
Or would it matter?
This question has nothing to do with political squabbles. I'm talking purely earth science effects: climate and such.

Nevermind. Google gave me the word 'Pangea' and some interesting discussions on this very topic.
So far it looks like we should be glad there are Seven Seas (and not just for things like The Seven Seas of Sinbad.)
