And what a depressingly sad comment about food supply. With 6 billion inhabitants we're running out of productive land, e.g. 'Global food crisis looms as climate change and fuel shortages bite - http://www.guardian.co.uk/environment/2007/nov/03/food.climatechange'. Already we're using almost 80% of land that could effectively be productive so where is the food for the projected extra 3 billion coming from.
Just because you can wander into Tescos to buy food to gorge yourself doesn't mean we're not approaching a global food crisis (I'm assuming you don;t live in the Sudan because you'd understand the impact of Malthus' ideas already).
