The Optimum Population Trust believes that the only solution is to gradually decrease the global population by .25% a year. Rosamund MacDougall told us that migration should also be limited in order to bring down UK population down to half its current levels.

But could such pressure work elsewhere? Or will technology provide the answer to a rapidly increasing global population?
