Who cares? you may say. Well, in Britain, The Carbon Trust cares. It determines the carbon footprint of specific food stuffs and urges (just wait, government urging inevitably becomes statute) that you modify your eating habits.

For instance, did you know that Coca-Cola in less damaging to the environment that a smoothie? Or that Cadbury chocolate generates about half the CO2 as the same weight of chicken? So much for “healthy” foods.

The unintended consequence of this is easy to see. After everyone forsakes bean-sprout smoothies for Coke and a roast chicken for chocolate, it’s not only their footprints that will get bigger.

How long before the Obama Administration begins telling us how to live and eat. Oh, wait. It already has.
