We all know that plants absorb CO2, give us O2, aka oxygen, and remove pollutants from the air -in effect scrubbing it up a bit. But a new study found that trees and other deciduous vegetation absorbed roughly a third more pollution than previously expected. The research, led by scientists at the National Center for Atmospheric Research (NCAR), used direct observation, gene expression studies, and computer modeling to show that deciduous plants absorb about a third more of a common class of air polluting chemicals than was previously suspected.
