Meat Free Mondays, continued.

A friend shared an article on Facebook with the following facts about beef:

Pound for pound, beef production generates greenhouse gases that contribute more than 13 times as much to global warming as do the gases emitted from producing chicken. For potatoes, the multiplier is 57… Producing the annual beef diet of the average American emits as much greenhouse gas as a car driven more than 1,800 miles.

The reason for this has to do with the fact that cows emit methane, which has ‘roughly 23 times the global-warming potential of CO2′.

No more burgers from vans for me. And I hereby limit myself to one steak or roast dinner a month.

Someone else pointed out to me, however, that even Guinness isn’t vegetarian:

Guinness was the winner of this year’s Vegetarian Society Imperfect World Award, for its lack of vegetarian-friendly credentials – like many cask ales and stouts, it is fined with isinglass. Isinglass is a form of collagen, and hails from the swimbladders of fish.

That one would be a bridge too far for me. I’ll take comfort in the fact that it seems unlikely that extracting isinglass contributes much to the warming of the world.
