the UK from its own resources, allowing for organic agriculture and
producing enough biofuel etc has to go a long way down, perhaps to six or
seven million?


You cannot reduce the population to 10% of current levels without a cull,
reducing birth rate ends with an unviable age profile.
Unfortunately if a cull was implimented we would end up only with
politititions and their families left as the commitee set up
would decide the most important post apocolypse facility would be a
really strong administration.
