Cutting the Cow Burps

Available for over a year

Cattle emit huge quantities of planet-warming methane. But they can be stopped! Tom Heap meets Eileen Wall from SRUC, Scotland's Rural College who introduces him to a host of cunning carbon-cutting ideas- from seaweed in the feed and gas masks for cows to barns that can convert methane into energy to power the farm. Tom is joined by Tamsin Edwards of King's College, London to calculate just how much difference these ideas might make to our warming Earth. Are those the best answers or should we all be persuaded to cut our meat consumption? Producer: Alasdair Cross Researcher: Sarah Goodman Produced in conjunction with the Royal Geographical Society. Particular thanks for this episode to Professor Vincent Gauci of University of Birmingham and to Dr Michelle Cain of Cranfield University.
