Australian researchers are planning to create enviromentally friendly cows and sheep? Does anyone else find this ridiculous?
Are you implying that Australians in particular are ridiculous or that the idea of "environmentally friendly" sheep and cows is ridiculous? Because cows and sheep are already environmentally friendly or because they cannot possible be made so by Australians? some caution about the possible ill effects of altering an animal's "natural" flora is certainly justified.
