CBC — the Canadian Broadcasting Corporation — has a new series on air called Diet for a Hungry Planet: How our World Eats. I’m busy listening to the first programme right now, and while it is pretty corny, it is also very informative. Although the focus is on Canada (and why shouldn’t it be?) the ideas being discussed are applicable everywhere. If nothing else, they’ll provoke discussion, I’m sure. Be warned, though, that if you listen direct from the browser page (as opposed to downloading a podcast version and listening to that), if you navigate away from that page the show will stop and you’ll have to go back to the beginning.
