No worries, I can take it.
I have a given scope in which I have to complete my survey and just limited time. I agree, there can always be done more. But in my context, this is what is possible for me.
And to be clear, my point is not necessarily that eco resorts are better. My interest is soley the experience with coral bleaching and how it affects your travel behavior. Unfortunatly a lot of diver "need to see a place, before it's gone" and don't realize they are part of the problem. Overall the Dive industry seems to be very sustainable (if you take into account, that a lot of people love the environment and want to protect it) BUT if you take a plane 5 times a year to get half around the globe for a few days of diving, you play a part in CO2 emissions which will kill the coral in the end.
There are enough studies on the environmental aspects of diving, I am looking at the touristic approach and the travel behavior.
The only impact I see is in training areas where student walk on the corals. I’ve worked on marine surveys where the financial backer (The Smithsonian Institute) has stated up front the conclusion must support Global Warming or the research scientists wouldn’t get further funding.
