India is discovering a miracle cow: The Vechur. It’s the smallest bovine in the world, standing less than three feet tall. But Indian scientists now believe it could have a big future in global dairy production, after a study of its unusual ability to withstand extreme heat and drought unexpectedly showed that it also emits far less methane than typical dairy cows, compared to the amount of milk it produces. The Kerala state government, which is funding the research, hopes the discovery could have important implications for the fight against global warming, if production is scaled up. Livestock emit more than one-third of all released methane, which warms the world 20 times faster than carbon dioxide.
