Researchers in Australia discovered that limu kohu (Asparagopsis taxiformis) can reduce methane emissions in cattle. In one Hawaii experiment, the reduction reached 77%. The World Bank predicted the industry could be worth ~$1.1 billion by 2030. As of 2024, preparation included three stages of cultivation and drying. Australia's first commercial harvest was in 2022. Agriculture accounts for 37% of the world’s anthropogenic methane emissions. One cow produces between 154 to 264 pounds of methane/yr.
