Eat 'Roo, Save Planet, Aussies Told

The Australian government's chief climate-change adviser says emissions could be drastically reduced if farmers and consumers switch from beef and lamb to kangaroo meat, the Australian reports. The marsupials emit much less methane than sheep and cows, the professor argues, and, as Australia heats up, are much better able to thrive in parched rangelands.

Kangaroo is becoming a "more and more accepted everyday meat," an industry chief said this week, but skeptical ranchers say the switcheroo is unlikely to happen soon. "If there's still a market for kangaroo meat in some areas, all well and good," one told Australia's ABC News. "But the thought of complete replacement, well, we just do not see that happening."
