One of the major sources of GHG methane has been reported to be contributed by cow farts. Up to 20% of methane emissions related to human activity are produced by global domesticated cattle. To control this problem, researchers at the James Cook University in Australia have invented an algae cake as feed for the cattle to reduce the methane emissions.
The starch rich, cellulose reduced algae is easily digested by cows and the creation of the mix serves as a sustainable option on various levels. As algae absorb carbon dioxide better than other plants, fish farms can grow it as a natural water cleanser. The algae can also be harvested for bio fuel and additionally they make great cattle methane reducing feed. Research is also on to develop an anti methane vaccine for sheep and cows.
