Ever watch Logan's run?

Na, seriously there are lots of ways from immigration control to controversial restrictions on births......With future tech such as the anti aging technologies we are close to making breakthroughs on we are likely to need something.....our population is rocketing and the world's population is generally.

There are underground cities or even further in the future floating ones.

But feeding this human expansion is going to be another problem.....again....technology will answer that or it's going to be horrible.

Transhumanist technology and post-scarcity technology.

I think we're rapidly approching a point where we can erradicate some aspects of physical death, through the use of bio-technology (digital conciousness, synthetic organs and cloning technology, will soon be able to replicate an entire person, with matching DNA, whilst cybernetics neurotechnology is rapidly becoming common place, eventually to the point where we could reasonably be possible to first transplant human brains into new bodies, and then potentially construct artifical means of storing and transfering memory as data contstructs.

Effectively a form of immortality. Can't cure the terminal disease, grow a new body from DNA and transplant yourself (biologically, or cybernetically) into a 21 year old body - eventually other bodies, any body, gender etc.

Related to this the technology to manipulate atomic structure and subatomic scale, will render the notion of value pointless, which is a potential crisis for society, as it renders capitalism redundant (as if you can manipluate on the atomic and subatomic scale, you can turn anything into anything else - creating a post-scarcity society.

Lovely.
Births are already being controlled but the effects won't be see for a couple of centuries and by then the population will be near 20 billion.

We will need a lot moe fresh water and food but can you imgine a population of triple what it is now co existing?
War, famine, disease on an a scale never seen before.

That's only a temporary resolving.....and not a particularly good method neither.

The only long term answer is birth control. Pandemics are only a temporary, although a 50% reduction in population would help in the short term.

Well on a reasonable, objective scale, its resetting the clock. Something reasonable virulent like flu/cold virus, airborne and with a medium incubation period, could end up infecting 50-75% of the worlds population and probably killing a further 50-75% of those infected.

Of course we need a more reasonable solution. I'd suggest that randomly steralising say 80% of the worlds population might resolve the situation within a generation - without actually killing anyone.

Of course now were in 'Utopia' terrotory
