An Australian scientist has said that eating kangaroo burgers could help cut greenhouse gas emissions. The scientist Dr George Wilson says that removing seven million cows and 36 million sheep by 2020 and replacing them with 175 million kangaroos could lower greenhouse gases by 3% a year. Currently sheep and cattle produce 11% pf Australia's total greenhouse gas emissions but kangaroos in comparison produce very little methane. Apparently kangaroos taste a little like venison. It sounds very interesting I wonder if you can get kangaroo in Sainsbury's?
