Food & Wine magazine posted an interesting story today about some recent research by Australian scientists which they claim shows that feeding cattle a diet with seaweed in it (as little as 2% is the claim) the methane output from the cows is significantly reduced.  Since Ireland is an island surrounded by the sea, Irish farmers are eager to put this to the test, since seaweed is abundant there. You can read more about it here. I’ll be interested to see if this pans out, since livestock production of methane is a significant contributor to the build-up of greenhouse gases in the atmosphere. So far most of the testing seems to have been done on grass-fed cows.
