Sydney - Australians were urged on Tuesday 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 more than 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 on Wednesday 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."Eat a camel today, I've done it," he told the national AAP news agency."It's beautiful meat. It's a bit like beef. It's as lean as lean, it's an excellent health food."
