Kangaroos don't emit methane in their farts*.
So, what the boffins say is that Aus should reduce their sheep and cattle and replace them with kangaroo$.
The marsupials, it turns out, have the potential to be the Prius of the nation's farmlands. A scientific paper in the international journal Conservation Letters reports that expanding the kangaroo industry would significantly decrease greenhouse gases.
It has long been known that hard-hoofed sheep and cattle have caused land degradation across the continent.
Dr George Wilson has an idea, it could be a winner.... if you like 'roo.
"Reducing cattle and sheep populations and increasing the kangaroo population on the rangelands to 175 million to produce the same amount of meat by 2020 would lower [greenhouse gas emissions] by 16 megatonnes, or 3 per cent of Australia's total emissions," the paper says.
The authors argue the increase in kangaroo populations from 34 million to 175 million would be made possible by the decrease in sheep and cattle numbers.
The paper says the carbon dioxide equivalents saved from 2007 to 2020 would be worth $655 million. "If a national [emissions trading scheme] requires livestock owners to purchase carbon permits to remain with cattle and sheep, landholders would have a stronger incentive to use kangaroo as low-emission meat."
The photo at the top is one I took just a few kilometres from home, only about one kilometre from town. There are three kangaroos in the photo, four if you count that the one on the far right feeding has a joey in her pouch.
*I'm pretty sure their shit doesn't stink, either.
