You actually have kind of a point, seph. Scientists say that since the world is so overpopulated, we will likely only last until about 2050 before the planet becomes uninhabitable. That's if the world's population increases steadily like it has been. I think that's the right date.... I might have it confused with something else.
2050 seems too early seeing as big parts of planet earth aren't loaded with humans yet
truely those aren't that great of places but i would assume that if the rest of the world becomes uninhabitable steps will be preformed
i would think 2300-2500 is a better date.
allowing the human population increasment to even slow down a bit
however the smell of war is in the air
it's only a matter of time before iran and countries like it will try to attack the "free world" a little bit harder.
the 3rd world war seems to be nothing but a matter of time
after that half of the world population will probably be eliminated (thanks to the usage of nukes for both sides)
and then... then we might last until 2500 and then there would probably be a big red button that kills everyone in the rate weaponery evloves nowadays mainly due to endless wars.
