New report out by the Food Climate Network, on the environmental impact of eating meat. But I think we're still a long way from winning - or even beginning - the public debate.
And here's what Boris Johnson thinks: "It's not eating meat that does the damage. It's the huge and remorselessly growing number of people who want to eat it." It's over-population we really need to tackle, says father of four, Boris. I like the suggestion in one of the comments that the obvious solution is therefore to allow the meat-eaters to eat vegetarians.
