Research in Ireland has shown that seaweed can prevent cows and sheep from expelling so much methane

Research has shown that marine algae can prevent cows and sheep from expelling so much methane. Ireland is already testing the method. Scientists are combing Ireland's west coast for seaweed to feed cows and sheep, after research has shown it could prevent animals from expelling so much methane, which is highly harmful to global warming. The project, coordinated by a state entity linked to agriculture, is taking advantage of the fact that the seaweed harvesting industry is growing and looking for new markets, while revitalizing centuries-old traditions. But some are skeptical that seaweed feed additives — or any quick technological fix — can sidestep the need to reverse an increase in Irish cattle numbers if the country wants to reduce Europe's highest per capita methane production. until 2030. About 20 species of seaweed, most of which from Ireland's windy Atlantic coast, have been tested by researchers, while dozens more have been collected by project partners in Norway, Canada, ...
