Meat is murder? More like suicide, argues Planeat film | Damian Carrington | Environment | guardian.co.uk

...meat has a very heavy impact on the planet, both directly and via greenhouse gases. So if we all want to sit down to eat without killing ourselves or the planet, we in the west will need to eat less meat and dairy.

I find it hard to fault the logic in that, and I am not alone, with the Intergovernmental Panel on Climate Change chair Rajendra Pachauri, economist Nick Stern and the United Nations Environment Programme agreeing. I'm not going to become a strict vegetarian, at least not yet, but I have given up meat at lunch.
