Save the planet - Eat a kangaroo (their farts are green).

Skippy could come to the rescue once again. Only this time old Skip could save the entire planet. Scientists have discovered that Kangaroo flatulence does not contain the greenhouse gas Methane. It's all down to the bacteria living in the Kangaroo's stomach, and scientists are trying to find a way to transfer the bacteria to cattle and sheep. Another plus point is that the bacteria is also 15% more efficient at digesting food, which would mean a reduction in feed costs.

It could take several years to develop a method of transferring the bacteria, so in the meantime scientists are recommending eating less beef and lamb in favour of good old Skippy. Peter Ampt of the University of New South Wales's institute of environmental studies said: "It's low in fat, it's got high protein levels it's very clean in the sense that basically it's the ultimate free range animal. "It doesn't get drenched, it doesn't get vaccinated, it utilises food right across the landscape, it moves around to where the food is good, so yes, it's a good food.''

I'll have a leg.
