Some might argue that this is a problem. I would like to offer up some simple facts and mathematics.
World Population = 6,773,234,966
Land Mass of Earth = 57,491,000 Sq. Mi.
Land Mass of Australia = 2,968,000 Sq. Mi.
1 Sq. Mi. = 639.9974 Acres
Acres of Land on Earth = 36794090523.4
Acres of Land on Aust = 1899512283.2
Acres per person in Australia = 0.28044387840302187443706644326681
Acres per person on Earth = 5.4322772955755156951689308928073
Are you reading that? I read that as, if every single person on earth, was in Australia, each could have more than a 1/4 acre... family of four, 1 acre.
Now, that may not be a alot, but that is the population of earth with in the boundaries of Australia. If you look at the same info globally, there is enough land for every person to have over 5 acres a piece. Every person from infant to elderly.... 5 acres!
Yes, I understand that there is a considerable amount of desert, etc in Australia. I hope that you see my point.
Also, because you will be asked if you choose to tell this to someone else.
Arable Land on Earth = 12,000,000 Sq Mi. (as in 4x the size of Australia).
Then you throw in the fact that we are a people that are inventing (rediscovering) ways to grow fish with plants year round in cold places and/or creating food forests in deserts and on mountains, and other considerably nonarable lands.
over managed, definitely
Overpopulated, Myth Busted
Math made easy.
