Australians should replace beef and lamb on the dinner table with kangaroo to fight climate change, Prime Minister Kevin Rudd's chief climate-change adviser says.
Professor Ross Garnaut has suggested in his final report on climate change that the nation's farmers should switch to the low-emission meat.
He also suggests Australian families should give up beef and eat more kangaroo.
"Sheep and cattle production is highly vulnerable to the biophysical impacts of climate change, such as water scarcity," he says.
"Australian marsupials emit negligible amounts of methane from enteric fermentation. This could be a source of international comparative advantage for Australia in livestock production.
"For most of Australia's human history of around 60,000 years, kangaroo was the main source of meat. It could again become important."
