Australians were urged to eat camels to stop them wreaking environmental havoc， just months after being told to save the world from climate change by consuming kangaroos. A three-year study has found that Australia's population of morethan a million feral camels--the largest wild herd on earth-is out of control and damaging fragile desert ecosystems and water sources. The Desert Knowledge Cooperative Research Centre， which produced the report， plans to serve camel meat at a barbecue for senior public servants in Canberra to press its point. Report co-author Professor Murray McGregor said a good way to bring down the number of camels was to eat them. \"It's beautiful meat，\" he told the national AAP news agency. \"It's a bit like beef. It's as lean as lean， it's an excellent health food.\"
