Scientists are trying to fight global warming by changing animal flatulence. Emissions from livestock reportedly account for up to half of greenhouse gas emissions (http://news.yahoo.com/s/afp/20071206/ts_afp/australiaclimatewarmingkangaroooffbeat_07120601004 4) in some countries. Kangaroos have stomach bacteria that eliminate methane from their gas; scientists want to transfer these bacteria to sheep and cattle. Bonus: The bacteria could improve digestive efficiency by 10 to 15 percent, thereby reducing feed costs. Alternative proposal: Eat less cattle and more kangaroo meat: "It's low in fat, it's got high protein levels," and "it's the ultimate free range animal."
