When nature and science meets the environment

Kangaroo flatulence contains no methane ? Thanks to special bacteria in their stomachs.

And now the Australian scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas, in an effort to cut the emission of greenhouse gases blamed for global warming. But is the emission of greenhouse gases by cattle and sheep substantial to cause something as alarming as the emissions from motor vehicles, and smokestack pushing out CO2 ?

Oh, maybe in Australia, it's substantial where livestock flatulence contribute a surprisingly high percentage of total emissions. 14% of emissions from all sources in Australia is from enteric methane from cattle and sheep, claims a senior research scientist with the Queensland state government. And New Zealand, almost around 50% since it has got a much higher agricultural base.

Now, should we eat more roo meat, or beef? ;P
