Jesus, @Cavviesarethebest can you not just put your point of view without using a term of abuse? I'm not dumb, not even a little bit.
the implications of an aging population with a longer life expectancy due to medical interventions
Well one of the implications is that there is a diminishing work force, and not enough people to look after and provide services for the elderly. Too many people not able to contribute to the economy is going to be a huge problem.
an understanding of the environmental and infrastructure implications of an in increased population
What about the implications of a decreased population? You only have to look at what's happening in China to see the huge problems that could be in store.
an understanding of the real financial, physical and social implications of having children in the currentl social structure
What do you mean by that? You don't think people should have children because... ?
it’s not a cracking outcome for children to be born to support a greedy elderly population who can’t bear the notion of well managed immigration
Woah. So the elderly are "greedy"? And they don't want immigration? Have you actually taken a breath and asked yourself what you mean by this?
So people should stop having babies and instead we should encourage more immigration, in your view? This seems like a plan with an awful lot of flaws.
