How should we eat to reduce our carbon footprint and save the planet? Should we all give up meat? Or eat only meat that's reared on grassland which couldn't be used for anything else? Or maybe eat intensively-reared meat that grows so fast that it has no time to emit a lot of methane before it's slaughtered?

Aside from meat, how important are food miles? Some argue that food grown in hot countries and transported here by boat has a lower overall carbon footprint than
food grown in Britain.

Tom Heap chairs a debate from the Bristol Food Connections festival with four experts who have very different views, and present their own menus for low-carbon eating: Jasmijn de Boo, Chief Executive of the Vegan Society, Simon Fairlie, author of "Meat - A Benign Extravagance", Mark Lynas, environmental author, and Sean Rickard, agricultural economist.
