Carbon dioxide killing Great Barrier Reef, study finds
Carbon dioxide killing Great Barrier Reef, study finds Australian scientist Bradley Opdyke reports that
Australia's Great Barrier Reef is in great danger of being
destroyed by increased levels of carbon dioxide. Increased world
carbon dioxide levels are found to raise ocean acidity, thereby
halting the growth of coral. Not enough has been done to lower
levels of carbon dioxide emissions and if this trend continues, the
Great Barrier Reef may well be doomed. Other reports from Hawaii
and France published in the journal 'Science' agree with his
findings.
