Methane is a potent greenhouse gas which contributes to the climate emergency. Intensive farming can lead to cows contributing significantly to levels of this gas in the atmosphere. Antonia, Ellie and Jasmin discuss the latest research to reduce the amount of methane cows produce through burps and flatulence. They look at additives to cow feed, using seaweed as an alternative feed, and selectively breeding the cows. They consider whether people should eat less meat and look at cultural and geographical challenges to doing so.
