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:

More Mother Jones reporting on Climate Desk

AN IMPORTANT UPDATE

We’re falling behind our online fundraising goals and we can’t sustain coming up short on donations month after month. Perhaps you’ve heard? It is impossibly hard in the news business right now, with layoffs intensifying and fancy new startups and funding going kaput.

The crisis facing journalism and democracy isn’t going away anytime soon. And neither is Mother Jones, our readers, or our unique way of doing in-depth reporting that exists to bring about change.

Which is exactly why, despite the challenges we face, we just took a big gulp and joined forces with the Center for Investigative Reporting, a team of ace journalists who create the amazing podcast and public radio show Reveal.

If you can part with even just a few bucks, please help us pick up the pace of donations. We simply can’t afford to keep falling behind on our fundraising targets month after month.

Editor-in-Chief Clara Jeffery said it well to our team recently, and that team 100 percent includes readers like you who make it all possible: “This is a year to prove that we can pull off this merger, grow our audiences and impact, attract more funding and keep growing. More broadly, it’s a year when the very future of both journalism and democracy is on the line. We have to go for every important story, every reader/listener/viewer, and leave it all on the field. I’m very proud of all the hard work that’s gotten us to this moment, and confident that we can meet it.”

Let’s do this. If you can right now, please support Mother Jones and investigative journalism with an urgently needed donation today.
