And this is called the "greenhouse effect," because of a similar effect produced by the glass panes of a greenhouse, where plants are grown under controlled conditions.

Global warming is a fallout of the greenhouse effect, and hence controlling greenhouse gas emissions is a major task before the scientific community.

Australian researchers believe kangaroos, their national animal, could come in handy. For kangaroo flatulence contains no methane and scientists want to transfer that bacteria to cattle and sheep.

Kangaroos produce virtually no methane because their digestive systems are different.  

Scientists say the bacteria found in kangaroo’s stomachs makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.

"Not only would they not produce the methane, they would actually get something like 10 to 15 percent more energy out of the feed they are eating," said Klieve.

Even farmers who laugh at the idea of environmentally friendly kangaroo farts say that's nothing to joke about, particularly given the devastating drought Australia is suffering periodically.

Dr George Wilson, of the Australian Wildlife Services, urges farming them.

He also points out that kangaroo meat tastes better, “…excellent, not unlike venison - only a different flavour."

The country already produces 30 million kangaroos farmed by landholders in the outback.

But Dr Wilson is keen to see that population dramatically increased to produce the same amount of kangaroo meat as that currently produced by conventional livestock.
