I almost thought this was a joke when I first read it. But apparently (according to the Queensland government), cow flatulence, which contains methane, is responsible for 14% of Australia’s greenhouse gas emissions. Kangaroos have a bacterium in their stomachs that neutralize the gas, so attempts are being made into transferring this property to cows and sheep.

These are great LED replacements for halogens or fluorescents. I had a mix of CFLs and halogens around the house that i've been wanting to replace with low energy LEDs for some time and I've now...
Goes on smooth and easily, doesn't smear too much throughout the day. The color is great and the product is natural. I'd definitely buy it again!
I'm not a big drinker, and I'm even less of a vodka drinker. That said, this vodka is quite smooth and mixed well into a variety of cocktails. If I'm going to drink vodka, I definitely prefer...
Great product, saves a lot of water. You definitely have to use some elbow grease though.
It's one of my favorites!
Cows to become a little more like kangaroos…post #1 of 61/7/08 at 1:44amThread Starterpost #2 of 61/10/09 at 9:54ampost #3 of 61/10/09 at 12:30pm
Well there's an error in the article linked by gerda.
The livestock sector is by far the single largest anthropogenic user of land. Grazing occupies 26 percent of the Earth's terrestrial surface, while feed crop production requires about a third of all arable land. Expansion of grazing land for livestock is a key factor in deforestation, especially in Latin America: some 70 percent of previously forested land in the Amazon is used as pasture, and feed crops cover a large part of the reminder.
Nevertheless, this kangaroo bacteria reserach could certainly help reduce emissions from livestock. Cool stuff. But more importantly, we need to reduce our meat consumption (especially beef).post #4 of 61/10/09 at 3:16pmpost #5 of 61/12/09 at 12:15pm
This comes from the article:
Earlier this year, Newbold reported that a plant extract from garlic, called allicin, could dramatically lower methane output by between 25 and 50 per cent. While this would benefit the climate, nobody has yet tested whether it would affect the flavour of the milk and meat from these animals...
There is a simpler alternative. Two Australian biologists say there is a sure-fire way to reduce methane emissions without resorting to complex biotechnology: cut the number of cattle and sheep being reared and meet the demand for meat with marsupials.
Ha. I think the comment about garlic extract affecting the flavor of the milk and meat is funny. And regardless of whether or not we start eating kangaroos, beef consumption could definitely stand to be reduced. Crazy that Argentinians eat an average of 155 lbs per person per year.post #6 of 61/12/09 at 3:20pm
Yeah that's a perfectly good solution in Australia where kangaroos are basically a pest, but doesn't work anywhere else. Though you could do something similar and switch to a non-ruminant animal like pigs/pork, poultry, etc. Or better yet again, reduce meat consumption altogether.
Hmm, garlic-flavored milk. That could be weird.
