About this episode
Scientists have long known that cows are a huge source of the greenhouse gas methane, contributing up to four percent of emissions globally. But could there be a way to make cattle less -- ahem -- gassy? Animal scientist Ermias Kebreab talks through an ingenious solution to reduce methane-rich cow burps by feeding cattle something growing below the surface of the ocean: seaweed.

Solving the cow burp problem
Agriculture in the U.S. produces more methane than the American oil and gas industry, and the biggest share of that agricultural methane is from enteric fermentation – essentially cow burps. Cows and other ruminant animals release methane because of the way they digest food. And ... Show More

The methane hunters
Methane traps more than 80 times as much heat as CO2 over the short term. So we could make a real difference on climate change this decade if we could stop leaking so much methane into the atmosphere. But before researchers and regulators can figure out how to do that, the methan ... Show More
