A further look at coral reef destruction...David N - MSDT / Retired
August 16 at 05:58:43Your post prompted me to make a quick reply and then to do some further looking about. A few facts might be in order. The area at issue has problems far beyond
divers. http://sviva.gov.il/Enviroment/Static/Binaries/Articals/6-11_1.pdf If you look, you will see that the number of divers has declined drastically but the use of fish cages for commercial fish production is now the major source of pollution. Further, the scientist quoted in the CDNN article you cite is not primarily an environmental expert. His research deals with the perception of polarized light in
cephalopods and other marine animals. Expertise in one area does not necessarily confer expertise in another. Recreational diving and snorkeling can have a profound impact on areas of a reef - 7 mile beach on Grand Cayman comes to mind - but to completely muck up an entire area requires much more substantial factors. |
