Happy Sunday, TED Talks Daily listeners. It's Elise Hugh. As we often do on Sundays, today we're sharing a recent episode of another podcast from the TED Audio Collective, handpicked by us for you. This time from our podcast, Speed and Scale. Did you know that cows emit methane even when they burp? Livestock account for more

than 12% of the world's greenhouse gas emissions, but farmers and scientists have discovered a superfood

that might be the key to lowering emissions and raising healthier cows. In this episode,

hosts Ryan Panchatsaram and Anjali Grover investigate the mystery of

asparagus, a seaweed variety that removes methane from the guts of the animals who eat it.

The catch? There are only nine licensed growers in the world. Ryan and Anjali are joined by three experts to talk about the science behind this amazing

plant the benefits we're already seeing from animals who eat it, and the next steps for

scaling up its use around the world.

To hear more inspiring stories about the people accelerating solutions to the world's

greatest climate challenges, listen to speed and scale wherever you get your podcasts.

Now on to the episode right after a quick break.

Okay. Okay, Ange, our story starts with a dairy farmer. His name is Joe Dorgan. His farm is a mix of green pastures and rocky red coasts. About two decades ago, Joe noticed something strange going

on with his cows.

The ones who were eating seaweed by the beach were doing better than the ones who weren't,

the ones farther away.

Interesting. How so?

They were making more milk. They were better behaved.

And in Joe's words, they had rip-roaring heats, which means it's easy for them to get pregnant.

And in the dairy business, that's important because to keep making milk, they have to have babies.

So there's something in the seaweed that's special,

like a superfood for cows.
