<div>Life-extension. That's how to solve population
growth problems. Sounds counter-intuitive ("won't
that make things worse?"), but do the maths. Not
only will it reduce population growth, but it will
encourage people to behave more responsibly, and I
have to say, even though I hate the term,
'sustainably'.</div>

<div>I'm not sure it would reduce population growth, but
the rest of that sounds correct - so it would at least
reduce the problems related to population growth. <br>

<p>This assumes that extreme longevity will reduce the desire to
have children, which seems a reasonable assumption, given the
usual real reason for having kids (to look after you in your
dotage). Note the extreme difference between having an average
of 2.5 kids and 2. Note also that 2 kids per couple is no longer
'replacement rate', as there is no death. Of course there still
would be, but from accidents etc., not from ageing.</p>
<p>I'm afraid I can't show you the actual calculatons behind this
graph, I seem to have lost them, and am not competent enough to
recreate them myself, but I'm sure many people reading this are.<br>
