According to some new research the best way to eat, or the greenest at any rate, is to incorporate a small amount of meat into your diet – not to be an out and out veggie.
The treehugger article I just read says: “The recommended ‘dose’ for a sustainable small foodprint is to eat only about 2 oz cooked meat or eggs a day. A single serving of meat is often estimated to be about 3 oz, or the size of a deck of cards. (insert quick math calculation here) This, leaves you with eating about 2 servings of meat every 3 days.”
It adds the caveat: “Naturally, your specific foodprint depends on where you live, and the availability of such resources as soil, water, and sunlight. But, this work points out the benefit of having a diverse system of agriculture that takes advantage of your local area’s resources, tradition, and taste.”
So I think this backs up those who go for the ‘meat as treat’ diets, and also supports the suggestion that a diet that is not too heavily meat based is better than one which includes meat based meals every day.
My personal preference is to stick with vegetarianism, and I am concerned that this allows wriggle room for determined meat eaters, who like nothing better than scarfing a nasty bit of beef that’s been flown all the way from a brazilian rainforest… Welsh lamb is pretty good though (so I’m told).
