Global Acidity Increasing

You’ve heard about acid mine drainage and ocean acidification, but the problems don’t end there. After reviewing a slew of scientific papers from different disciplines, researchers found that combustion of fossil fuels, smelting of ores, mining of coal and metal ores, and application of nitrogen fertilizer to soils are all driving down the pH of the air, soil, and water at rates far faster than Earth’s natural systems can buffer. That could pose threats to both land and sea life. For a link to the researchers abstract visit https://gsa.confex.com/gsa/2012AM/finalprogram/abstract_207495.htm.
