Actually we ARE making wise choices, the question is are we making them quick
enough, and will things change.
In about 1980, the prediction for world population at the millenium was "12
billion likely, there's no way it'll be less than 8". Yet in 2012 we're not
even at that low estimate yet!
In order to maintain a stable population, each woman needs to have, on average,
2.2 children. In Europe, Britain with 1.8 has the most fecund population on the
continent. Even India, which is usually assumed to be "breeding
irresponsibly" I think the figure is now down to about 3.3. What with AIDS
and stuff like that, it is widely expected that Africa is likely to be the first
continent with an actually falling population, with Europe following shortly
after.
The reports I've seen say that, based on present trends, a REASONABLE estimate
for the world population in 2150 seems to be about 3 billion. Is that a fast
enough reduction? I don't know.
Cheers,
