"A P.E.I. farmer has helped lead to a researcher's discovery of an unlikely weapon in the battle against global warming: a seaweed that nearly eliminates the destructive methane content of cow burps and farts."http://www.cbc.ca/news/canada/prince-edward-island/pei-cow-farting-1.3856202
"Ruminant animals are responsible for roughly 20 per cent of greenhouse gas emissions globally, so it's not a small number," said Kinley, an agricultural research scientist now working at the Commonwealth Scientific and Industrial Research Organisation in Queensland, Australia.
"We're talking numbers equivalent to hundreds of millions of cars."
Kinley thinks it could take anywhere from three to five years to get a commercial animal feed to market. He says the biggest challenge will be growing enough seaweed.
"Agriculture stands to be one of the first to make major changes in the greenhouse gas inventory and so it's really a game changer if we can get this out into the market."
