A very disturbing report there, but nothing new. I notice their reasons for coral degradation were a little off:
the causes of coral reef illnesses, such as water pollution, flows of sediment from the land to the sea, and destructive diving activities,
Nice of them to blame the foreigners for destructive diving when in fact it is their own people on snorkeling trips that are not educated to refrain from standing on the reef and kicking the hell out of it. Divers are generally quite responsible under water.
Additionally they have left off the major cause of coral and marine life depletion which is fishing. There are a number of pristine spots down the coast south of Prachuab where coral is growing but they will be fished out within a few years if nothing is done about it. The coral reef is an entire ecosystem which relies on the fish to be there. Thai fishermen generally do not respect the ocean they depend on for their livelihood.
There are a couple of islands off the coast of Chumphon with good coral growth and I was pleased that they had designated the area a marine national park. What really made my blood boil is that they were all too keen to deprive the farangs of 200 baht to visit the islands but still allowed locals to anchor on the coral and fish using nets. Half of my diving was spent cutting fishing nets off the coral.
I've also witnessed fishing boats throwing huge bin liners of plastic and polystyrene into the ocean near Hin Daeng & Hin Muang - two spots with abundant coral and marine life that attract manta rays in the Andaman.
Only when Thailand stops its money grabbing and starts caring for its environment through education will these reports show something positive.
Interesting to see there were a couple of blue spots around the Bangsaphan area - this also goes against their reasoning as there is a steel mill, sediment run-off, and a lot of fishing that goes on in the area. I don't think the coral will be there for long, it is already suffering around Koh Talu however this is due to the ignorant snorkel trippers mentioned above.
