Cows are a significant source of methane emissions, primarily due to their unique digestive system. Milk and beef cows are ruminants, which means they have a specialized stomach chamber (called the rumen), which houses billions of microbes that facilitate the breakdown of fibrous plant material. The process is called “enteric fermentation,” and as these microbes work to digest the cellulose found in the cows’ diet, methane is produced as a byproduct. That’s a problem: The EPA identifies methane as being about 25 times more potent as CO2 as a greenhouse gas. Alga Biosciences leaps to the rescue, creating a new feed for cows that dramatically reduces how much burping goes on.
“Enteric methanogenesis, also known as cattle burps — is the single biggest source of anthropogenic methane emissio...
