Communication and competition are common occurrences among the plant world. Another brilliantly, almost inconceivable capability plants possess is the ability to recognize coexisting family members within their home range…. ;

Magnetized Wetlands and Acid Mine Drainage

– Magnetized Wetlands and Acid Mine Drainage Acid mine drainage is a problem that affects many states, specifically being an extremely large problem in Pennsylvania. Target ores often contain sulfides, which react with the air and water to form sulfuric acid. Sulfuric acid, being one of the six strong acids, completely dissociates and dissolves harmful metals in the surrounding rock. These harmful metals include arsenic, copper, iron, etc. The dissolved metals sink to the bottom of ponds, rivers, and streams; this causes acid mine drainage to be a perpetual problem…. ;
