The article focuses on the environmental impact of cows' methane emissions. Altogether, the 100 million cows in the U.S. are responsible for 20 percent of the country's emission of methane. The methane cows produce is more than 20 times more harmful than carbon dioxide. Scientists from Germany have invented a pill that they say could improve cow digestion.

    Surface water pCO2 and pCH4 measurements were made in Québec (Canada) during consecutive seasons from 2006 to 2008 in two boreal reservoirs and nearby lakes. The goal of this follow-up was to evaluate greenhouse gas emissions from the water bodies studied, through flux calculations using the...
