BBC Radio's daily "Farming Today" report on Friday 6th January 2006 begins with, There are seven and a half million people in the greater London area. They all need feeding. But what would happen if the oil ran out?" The segment covers the possibilities of war or catastrophic climate change bringing about energy shortages - what would happen to the transportation of food to London, not to mention the growing of that food? The report briefly discusses alternative fuels, as well as individuals growing their own food and farmers switching to organic methods.
