How to eat Joey, or kangaroo meat saves earth from global warming...

I was reading an article on the New Scientist, that said that a lot of meat eaters such as cows produce a great deal of methane, which contributes a great deal to global warming (the site claims 18%). Microbes break down the food into hydrogen, CO2 and fatty acids. Some microorganisms called methanogens consume to hydrogen and CO2 and produces the methane that is then excreted out.

Supposedly they are developing vaccines as well as feed additives that can reduce methane production (by absorbing the hydrogen with sunflower oil or coconut oil). There's also the possibility of using legumes to slow the growth of methanogens.

Something that was suggested is to eat kangaroos, which is supposedly a flavorful meat, that is low in fat. This means that you shouldn't really cook it beyond medium or even medium rare otherwise it becomes tough. I found a site that had a bunch of kangaroo recipes. It's hard to think that in Australia that kangaroos are a pest.

Interesting, if global warming becomes a real great issue, would it behoove governments to force people to become vegetarians?
