Cows with Gas: India's Global Warming

Madhur Singh, New Delhi (TIME)

Indolent cows languidly chewing their cud while befuddled motorists honk and maneuver their vehicles around them are images as stereotypically Indian as saffron-clad holy men and the Taj Mahal. Now, however, India's ubiquitous cows -- of which there are 283 million, more than anywhere else in the world -- have assumed a more menacing role as they become part of the climate change debate.

By burping, belching, and excreting copious amounts of methane -- a greenhouse gas that traps 20 times more heat than carbon dioxide -- India's livestock of roughly 485 million (including sheep and goats) contribute more to global warming than the vehicles they obstruct.

With new research suggesting that emission of methane by Indian livestock is higher than previously estimated, scientists are furiously working at designing diets to help bovines and other ruminants eat better, stay more energetic and secrete lesser amounts of the offensive gas.
