Kangaroo Farts Could Be Used to Fight Global Warming

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep.  They want to cut the emission of greenhouse gases blamed for global warming.

Thanks to special bacteria in their stomachs, kangaroo flatulence contains no methane.  Scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.

The usual image of greenhouse gas pollution is a smokestack pushing out carbon dioxide.  But livestock passing wind contribute a surprisingly high percentage of total emissions in some countries.

"Fourteen percent of emissions from all sources in Australia is from [intestinal] methane from cattle and sheep, "said Athol Klieve, a research scientist with the Queensland state government.

"And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said.

Researchers say the bacteria also make the digestive process much more efficient.  That 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," Klieve said.

袋鼠屁可抗全球暖化

澳洲科學家正嘗試在牛羊體內植入袋鼠胃，他們希望可以藉此稍減因其溫室氣體排放量造成全球暖化所帶來的指責。

歸功於袋鼠胃中的益菌，使得袋鼠胃的氣體內不含甲烷。

科學家們希望將這細菌轉植到會排放大量有害氣體的牛羊體內。

溫室氣體污染一般會聯想到煙囪所排放出的二氧化碳。但是，一些國家的溫室氣體總排放量中，家畜所排放出的氣體，出乎意料地佔了相當高的比例。

昆士蘭州政府負責研究的科學家克里夫提到，澳洲的總排放量中，有百分之十四是來自於牛羊的腸內甲烷。

而且如果你仔細看其他農業發展度較高的國家，如紐西蘭，事實上她還高達將近百分之五十。

研究員說這細菌也能促進消化，而這個發現將可以為農夫省下百萬飼養費用。

而牛羊將不僅不製造甲烷，而且事實上還會從所吃的食物中多獲得百分之十到十五的能量。
