I guess you could do the math on that Alaska thing.

All I know is the math is correct for this: There are 1.9 billion acres of land in the continental United States. 8 billion people, so that's a 1/4 acre more or less, for each person. Imagine the entire rest of the world empty! For farming, hunting, fishing....

There's def enough space no matter it's 6 or 10 billion around right now.
