Cow farts have become a surprisingly controversial topic these days. And no it is not about the ever raging debate about whether farts are funny or not; it is linked to a more serious environmental issue. Cow farts release a surprising amount of methane gas into the atmosphere.
This gas contributes to the current global greenhouse gas crisis so much that a 2006 United Nations’ Food and Agriculture Organization report claims cows "generate more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport." But recent research suggests that we might be able to reduce this number by feeding cows seaweed.
