Kangaroo - ancient answers?

I have always found Australia fascinating and have admired the way that they have embraced nature. People over the years have pontificated about what undiscovered cures may be available to us in the rain forests of the world. The human race has taken animals and bred in certain qualities and bred out others to achieve the farm animals that we have today. We have gained valuable food sources by doing this but what have we lost? It is now evident that kangaroos being primitive creatures untouched by man have a secret weapon. Their digestive system is the same as all other mammals with the exception that the bacteria in their guts create acetate which fully aids their digestion resulting in totally gas free bowels. They simply do not produce any gas whatsoever - they do not fart! Kangaroos therefore do not produce any greenhouse gasses and when that is compared to cattle - the average cow produces enough gas to fill a 40 to 45 gallon drum - approximately 250 litres of methane per animal, per day.
