Plants naturally absorb
carbon dioxide and
release oxygen, but certain plants also eliminate
significant amounts of benzene, formaldehyde and / or trichloroethylene.
According to a new study
of 28,000 measurements collected between 2000 and 2006 and analyzed by NOAA's CarbonTracker system, only about a third
of the
carbon dioxide is absorbed by
carbon sinks such as the soil and forests; a large portion
of it ends up in the atmosphere - but that still leaves a
significant amount unaccounted for.Interestingly, the CarbonTracker found
carbon emissions to be highest in the Midwest; that single region
released more
carbon dioxide than any other country - except Russia, China, India and,
of course, the U.S.
Carbon dioxide was found to be most readily absorbed east
of the Rocky Mountains and in northern Canada.
