Sorry, but life as we know it is doomed, and sooner than you think.


One question I have, is it going to be catastrophic or phased in? There
may be a weather related catastrophe, volcanic, earthquake, or human
started nuclear wipe out of millions, maybe billions of people.

Next, will it happen next week, next year, or in two centuries. I think
it will happen.

Natural resources will eventually be drained too.

The sun will eventually run out of hydrogen, expand, and burn the earth
to a cinder too.

When populations begin to exceed supply, you get shortages and price
hikes. At first these will be coincident with poor harvests. In poor
countries, like Ethiopia, that will lead to local malnutrition and
deaths from associated disease. As it gets worse, you will get people
dying of hunger. The world will be inadequately compassionate and
supply some aid but that will not turn back the tide.

As world populations grow further there will be more 'bad harvests'
because even average ones will no longer be enough.

Those countries that produce a surplus will sell their excess to those
in other countries that can afford to buy them. As more and more
countries cannot produce enough to feed their ever-increasing
populations, supplies to other countries in trouble will of course
diminish further. There will be protectionism. Countries that can
produce enough for themselves will keep their food for themselves and
will not share it. And people elsewhere will starve.

We in Britain will be in trouble then because, although we're rich,
money can't buy food from those who are starving themselves. And we can
produce here only enough to feed 50-60% of the current population.

So, keep an eye on the world population, see famines anywhere as just
the start, worry about reports of poor harvests anywhere, and see price
rises in the shops as an early indicator of things to come.

As for time scale, that's the curse of all futurologists. We'll be OK
for a bit, but can we support a world population increase from 7 billion
at the moment to over 10 billion by 2050? That's for you to decide, but
you'd better have a pretty good idea of where an extra 50% of cultivable
land is going to come from if you say yes. And then some after that as
populations expand even further.

Sorry to be so gloomy on a lovely Thursday morning, but it's inevitable.

The laws of supply and demand will restrict population growth (or
reductions) as that happens.

Once we get to the maximum population that can be sustained by the rest of
the world's food supply people will die of starvation to keep the population
in check

whether it is desirable to reach a state where X% of the world's land is
used for housing the population whilst 100-X% is simply used to grow food to
feed them is another matter

That theory worked well in stopping the Irish starving in 1850, didn't it

Oh wait a minute
