Who knew that bovine burping was a major source of methane gas and hence global warming? German scientists, that's who, and they've come up with a fist-sized pill to reduce it, along with the 4% of greenhouse gas emissions for which it is responsible.
The munchable, plant-based pill, when combined with a strict diet and special feeding times, allows cows to metabolize the excess methane in glucose production rather than burping it into the atmosphere. "Our aim is to increase the wellbeing of the cow, to reduce the greenhouse gases produced and to increase agricultural production," says Winfried Drochner, leader of the project.
