The Future

[AFTT47]

But can we revisit this population/immortality (or extended life span) question one more time?
OP, as of right now, the World Population stands at 7.5 billion - or just under.  During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.   That is a HUGE increase.  We really don't have the resources to handle our current population, and if it keeps rising, we're in trouble.  You propose extended life-spans (and greater levels of health, and more efficient healthcare, I'm assuming), which sounds quite lovely.  But Hanky is right.  With current population growth and extended life-spans, that population increase becomes a terrible problem.  
    A much, much . . . much! . . . lower birth rate would be absolutely required.  Or, as Hanky said . . . colonization.  Neither sound like a bad idea to me.  What are YOUR suggestions to solve the problem?

Space colonization would definitely be needed. A very low birthrate would sure be nice too. I don't know how a nearly limitless lifespan would affect people's drive to reproduce. I don't have that drive at all (I can't stand kids) so I can't empathize with those who do. Maybe with the time pressure gone, the urgency would be gone too. What's the rush when you'll always have time to do it later if you really want to.
