Adding a type of methane-inhibiting red algae directly to cow feces cut down methane emission from the poop by about 44 percent, researchers report.
Believe it or not, it’s a laudable goal. Cow feces is responsible for about 40% (yes, really) of methane production worldwide, and methane is several times more impactful as a greenhouse gas than carbon dioxide. I called bullshit (heh) the first time I heard these stats, too, but they’re real.
