I doubt the answer to world population crisis lies all with the UK. We're not having enough babies to replace the population as it is. What more do you want??
At no point did I say this. I quite specifically said 'not just in Britain'.
I think there's a way of feeding everyone on the planet - we already produce too much food that goes to waste - that can't be right. It's our politics of money at all costs and sod the actual needs of people that isn't right. Not the fact there are 'too many' of us.
This is true about the capitalist model followed pretty much everywhere, I agree, at this moment in time. But I didn't suggest there wasn't enough food now, or that there wasn't too much even. I asked how you suggest we feed 2, 3 or 4 times the current population, and for that matter where we would put everyone. A much bigger problem than a temporary imbalance between young and old in the UK. And a problem for which you haven't posited any solution.
This is the kind of argument right wingers push when it comes to birth control in 'poor' countries and from stopping the 'wrong sort' of people breeding in the western countries.
Quite probably but that doesn't alter the fact we are going to struggle to support the future world population if it continues to grow at the rate it is, notwithstanding the UK's falling birth rate. I'm in favour of voluntarily having less children, and later in life on average. This won't work, however, and at some point, in desperation and too late, policies of restricted childbearing will probably be put in place at which point there will end up being someone, somewhere in charge of stopping the 'wrong sort' of people from procreating.
And then when that doesn't work, nature (combatted, as you say, in some parts by the lucky/wealthy) will take it's course and the population will drop that way.
However we might rail against, nature, strive to control it, and seem sometimes to conquer it and exploit it, humans' existence on Earth has a lease. We can shorten it, or extend it, but we'll never be offered the freehold...
