she knows it's coming. she doesn't chase it like a cat does. 0h, she's... and the reading is 18 ppm. so it's been a while since she's had a lot of food. 0k, she's having a clean day. all right. thank you, eileen. now, one way to cut down on cow burps is to cut down on cows, of course. but in the meantime, did you know that there is a company that is working on a way to catch the methane as it comes out? how are they doing that? cow masks, of course. true story. the masks have fans in them which suck in the methane and oxidise it and the makers say they can cut the amount of methane released by half. cow masks, everybody. eileen, that is fascinating. thank you so much. thank you, team, and thank you, magenta. woo! lara. well, that went a lot more smoothly than it may have done! but what comes out of a cow could also be affected by what you put into a cow. this lot are eating feed created from seaweed found in the waters of hawaii, and its makers, blue ocean barns, claim it cuts emissions by 80%.
