A recent study, however, revealed that one significant source of air pollution in America is actually associated with corn. The researchers found that the fertilizer used to increase crop yields can cause a kind of air pollution called PM2.5 (Particle Matter 2.5 micrometers thick), resulting in negative health impacts for people living nearby. … Continue reading Clean Corn? Study Measures Effects of Air Pollution in Corn Farming

A team of Australian scientists lead by Rocky De Nys (James Cook University) discovered that a certain type of red seaweed, called Asparagopsis taxiformis, can decrease the amount of methane produced by the bacteria found in a cow’s stomach. Lauren Kuntz explains that methane is a very potent but short-lived greenhouse gas. Limiting methane produced by livestock, a major source of the gas, could help … Continue reading Seaweed May Cut Cows Methane Production
