Green Algae Beer Fights Climate Change by Reducing Methane Released by Cows

Young Henry's Brewery in Australia is using green algae to make an environmentally friendly beer. Despite the tanks of bubbling algae, co-founder Oscar McMahon told CBS News, "The algae is just part of the production process, it never touches the beer." During the beer’s fermentation process, the microalgae ingests the carbon dioxide released instead of letting it go out into the atmosphere. Leftover algae goes into cattle feed, reducing the methane gas released by cows' farts and burps.
