Can seaweed curb methane from cows

Evan Talty, the Managing Director of Wild Irish Seaweeds, turns the Carrigeen Moss (Chondrus Crispus) seaweed in a field on his seaweed farm where it has been laid out to dry in the sun, in the County Clare village of Quilty. 

Scientists are combing Ireland's west coast for seaweed to feed to cattle and sheep after research showed it could stop them breathing out so much climate-warming methane.

The project, coordinated by a state agriculture body, is tapping into the country's growing seaweed harvesting industry, which is seeking new markets as it revives centuries-old traditions.
