Their plan: to feed the underwater plant to cows and sheep in an effort to make the animals less environmentally destructive.⁠⠀ ⁠⠀ The belching and flatulence of livestock release large quantities of methane and make up around 4% of global greenhouse-gas emissions, according to data from the United Nations’ Food and Agriculture Organization. That’s equivalent to the amount contributed by Japan and Germany combined.⁠⠀ ⁠⠀ Seaweed alters bovine digestion, reducing the methane an animal produces by 80% or more, according to scientists at the University of California, Davis, and Australia’s national science agency. It is one of the plants and chemicals that meat and dairy businesses are experimenting with to reduce their contribution to global warming.⁠⠀ ⁠⠀ Now, the focus is on finding ways to cultivate asparagopsis at sufficient scale to make a dent in global cattle emissions. It is too early to know what seaweed-enhanced feed might cost, but it is possible farmers could offset higher feed costs with improved cattle feed conversion or through carbon credits in certain markets.⁠⠀ ⁠⠀ Read more at the link in our bio.⁠⠀ ⁠⠀ 📷: @crerar_photos_words for @wsjphotos」11月16日 4時04分
