Making cows pass kangaroo gas

Via DoL: "Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid to cut the emission of greenhouse gases blamed for global warming, researchers say. Thanks to special bacteria in their stomachs, kangaroo flatulence contains no methane and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas."

Not everyone agrees that bacteria transfer is the simplest option. Instead, they suggest just eating kangaroos instead of cows.
