It’s the time of year when many people make New Year's resolutions – so we thought we'd look at some of your environmental resolutions. The first of which might be to eat your pet, if authors Brenda and Robert Vale are to be believed. Also on the show - carbon offsetting may be a good way to ease your guilt over flying, but what happens to your cash? We also sing the praises of bamboo and learn how not to argue with climate sceptics.

The art of arguing with climate change deniers
The past year has been a challenging one for climate change deniers, as scientists from around the world come forward with ever more evidence of global warming.
