Solution:
The only way the population is going to be bought down to sensible and sustainable levels is a global virus with a 1% or less survival rate
That would bring global population down to 80 million or so.
Which is still more people than live in the UK & Eire today.
I seem to remember that the majority of Europeans can trace their DNA back to only 3 women, so maybe a survival rate of 0.1% would be OK (800,000 people globally, or the population of Suffolk)
