Scientists Hooked Up an Inflatable Bag to a Cow Stomach. The Timelapse Video Is Insane.

Now we can finally see just how gassy these beasts really are.

Specialty belch-backpacks help show just how much methane cows produce every day.Discovery


Cows are gassy beasts. And this gas is bad for the planet. Last year, my colleague Josh Harkinson detailed just how dangerous this gas has become in our atmosphere:

Cows are already the nation’s single largest source of methane, a greenhouse gas produced by oil extraction, decomposing trash, and the guts of grazing animals that’s as much as 105 times more potent than carbon dioxide. A single cow farts and belches enough methane to match the carbon equivalent of the average car. According to a 2006 United Nations Food and Agriculture Organization report, the world’s 1.4 billion cows produce 18 percent of the world’s greenhouse gases—more than the entire transportation sector.

Our hunger for beef is a big problem for the climate: More cows, more methane, faster warming. Now we have a sensational new visual way to understand exactly how much methane we’re talking about, thanks to a new documentary called Racing Extinction, which airs on Discovery Channel Wednesday night in 220 countries and territories around the world—a date designed to coincide with the early days of the high-stakes UN climate summit, where diplomats are attempting to forge a new global deal to limit greenhouse gas emissions.

To measure just how much a single cow emits every day, scientists at the National Institute of Agricultural Technology hooked up inflatable plastic bags to cows’ stomachs. Then they fed them. And then, they watched the methane bags inflate. Check out the time-lapse:

Look, they even have special belch-backpacks:

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
