Hundreds of generations? That's in the thousands of years. Our population has increased from 6 billion to 7 billion in just 13 years.Vuljatar said:We've got, at a minimum, hundreds of generations before it would become a real concern
Bugger it, lets say a flat 100 generations, and 2.4 children average (world average is still higher than this by the way; world growth in 2011 was at 1.1% which equates to about 2.63 children per couple with a 25 year generation). Starting at todays 7 billion, assuming no dire catastrophes e.g. world starvation (lol!). After 100 generations we would have:
7,000,000,000 * 1.2^100 = 579,725,821,654,101,851
That's around five hundred and seventy nine quadrillion, seven hundred and twenty five trillion, and eight hundred and twenty one point six billion people.
The point is we're never going to see that, and we'll be lucky to see anything like 12-13 billion, because we just don't have the resources to feed that many people. The population will decline by starvation if by nothing else. But do we step in to stop such a thing? Left unchecked, there's one universal truth about humans from all across the globe: we'll never stop shagging.
