Over 4 million apples and over a million and a half bananas are thrown away in Britain every day. This video from Newsnight is excellent on the external costs of the food we throw away - estimated by some to be worth around £8 billion a year. Should we actively encourage food scavengers? What are the strategies we should be adopting to reduce the amount of food thrown away? This is a good topic to use to teach evaluation skills for AS microeconomics.
