Well it seems you both have misunderstood the obvious point, it wasn't on the reasons for urbanisation, it was the fact that the UK can EASILY increase its population (housing) in urban areas without building OUTWARDS as other countries have managed to do so. But as i mentioned above, the planning laws and local residents balk at any attempt to increase urbanisation in their back yard.
Sorry offtopic. Only point is they charge more for 1 bed flats than they do for 2-3 bedroom affordable houses. Two flat towers near me were demolished because no one wanted them, and the target population couldn't even afford them. £99 a week for 1 bed flat vs £63 a week for 2 bed semi, hmm, which one should I apply for?
More population needs more housing, more food, more health services, more recreation, more transport, more road congestion, last I checked we are struggling with at least a few things on that list.
And yes we have a lot of selfish people that still want to make a lot of babies, like 4+. They also tend to be the same race as me which isn't white. UK is going to crash at this rate with overpopulation just like China previously did.
