Adding pink seaweed to cow feed eliminates their methane emissions
One of the major contributors to greenhouse gases is the methane that cows belch up as they break down cellulose, but five years ago, research from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) found that adding small amounts of a pink seaweed called Asparagopsis to cows’ diets eliminated the gut microbes responsible for methane production and “completely knocks out” cows’ methane emissions.
Asparagopsis grows on the coast of Australia, and cows actually seek it out and eat it without encouragement. Replacing 2% of cows’ feed with Asparagopsis is sufficient to end their methane production.
Researchers at the University of the Sunshine Coast are trying to ramp up Asparagopsis production to scale to meet a potential global market for it.
