I was watching something on TV the other night which touched on population / urban growth in certain parts of the world and decided to take a look at the figures.

Pretty amazing really.

Click on the 1950 header to order it by 1950 population then glance to the right to see the change over time.

Click on 2025 then glance left to see where the likes of Delhi, Shanghai and Mexico City have come from.

No. 428 Nay Pyi Taw in Myanmar (wherever the hell that is). How can it go from a population of zero from 1950 all they way up to 2010 then suddenly have over a million people.









Too many damned people on the planet that is for sure.
 
On the plus side the population of Liverpool has gone down :D :exit:

unfortunately, it means they are spreading out a bit more ;)

Population is by far the biggest threat to the planet.

This is the issue that the greens don't get. Too many people will lead to not enough food and ultimately more conflicts. This is the threat to the planet, not global warming.

If anything, global warming could help by reducing population. Mother Nature knows best! Obviously that can't be a policy and aside from colonising Mars there is no answer to the issue.
 
It seems amazing to me that in just my lifetime (I was born in 1962) the population of the planet has more than doubled.

Viewing a graph of the world's population over the last 1000 years reveals slow, steady growth until you get to 1950 and there is the beginning of a massive spike on the graph which shows no sign of declining at all as countries like China and India industrialise themselves.

Politicians speak of an 'immigration' crisis in the UK, when they should be speaking of a 'population' crisis affecting the whole planet. It's the 'elephant in the room' that won't be addressed.
 
I've done my bit to reduce the population - or at least avoid increasing it!
 
The biggest future problem is not necessarily population growth - it is the aging population.

Worldwide, the average life expectancy is within a few weeks of the typical retirement age - it will likely increase to approx 30 years after retirement age according to the long range projections.

People living older is surely a good thing - surely good health and longevity go hand in hand?

For the individual it is without a doubt.

The issue is more of an economic one - how are they going to be supported. Current global life expectancy is very close to the typical retirement age. Now if the global life expectancy increases, then the ratio of tax payers and workers to the elderly swings massively, causing a massive burden to future workers. It may mean that the increased living standards experienced by almost every generation for the past few hundred years stagnates or even significantly reverses.

Regarding a future population boom, most models do not predict this, but there are so many variables that if changed by even a small amount can make a massive difference to the outcome. There was an interesting 'more or less' show talking about population growth and life expectancy - I think it was this edition. PS I highly recommend 'More or Less', along with '5 live Science', two of the most interesting radio shows / podcasts I have listened to.
 
Surely if people are staying healthier longer then they can stay productive for longer. A lot of people work beyond retirement age and rightly so if they wish to.

Very possibly. But the current expectation of retiring at circa 65 and having a reasonable pension will likely disappear meaning you have to be productive longer.

Also, that is assuming no mental degradation - that is a growing problem with the increasing prevalence of conditions like alzheimers and other forms of dementia.
 
needs careful interpretation though - a lot of city populations have grown due to people migrating there rather than having more babies - e.g. Shenzhen was a village in Hong Kong and after we handed it back in 1997 the Chinese made it into a major financial centre. And I have to say, since when was West Yorkshire a city? :thinking:
