Each year, livestock production pumps out greenhouse gases with the equivalent warming effect of more than 7 gigatons of carbon dioxide, roughly the same global impact as the transportation industry. Nearly 40% of that is produced during digestion: cattle, goats, and sheep belch and pass methane, a highly potent, albeit relatively short-lived, greenhouse gas.
If the reductions achieved in the UC Davis study could be applied across the worldwide livestock industry, it would eliminate nearly 2 gigatons of those emissions annually—about a quarter of United States’ total climate pollution each year. Ermias Kebreab, an animal science professor at UC Davis who leads the work, is preparing to undertake a more ambitious study in the months ahead, evaluating whether smaller amounts of a more potent form of seaweed can cut methane emissions even further. Meanwhile, some businesses have begun to explore what could be the harder challenge: growing it on a massive scale. Read more on MIT's Technology Review.
