Some environmentalists have long tried to blame the decline of coral reefs on man-made global warming.  But now comes word from the Florida Keys that a very common bacterium is actually the primary villain.  According to the Environmental News Network, a study by the National Academy of Sciences found that white pox disease, which has already killed most of the magnificent elkhorn coral on some reefs near Key West, is caused by a fecal bacteria found in the intestines of humans and animals.  Elkhorn coral is an important Carribean species, providing both food and shelter for many reef dwellers.  But while the source of the bacteria is still unknown, one thing for sure is that it didn’t come from the greenhouse gases of America’s tailpipes and smokestacks.
