In my opinion, this is a bit of a complicated issue. I can see both sides. Humans simply disrupt the environment as we carry about our daily lives and interact with nature. Snorkelers, scuba divers, trop collectors, sport fishermen, hikers, etc. We always have an impact. If you go to the zoo, sea world, the Hilton dolphin experience...you are supporting a far more sinister business...Of course, this is my opinion and I fully respect other people's opinion. There are guidelines in place for viewing dolphins. (Don't know why you can drag a marlin through the water for hours of fun and torture...but you can't swim near a dolphin...but, whatever...) Most of the companies do their best to follow these guidelines. After all, they do really like and respect the dolphins. It gets tempting to get customers a little closer...or customers themselves swim too aggressively and so infringement on the regulations does happen. It's an interesting topic. Over and over again animals such as immature sport fish and "teenager" sharks of all kinds are brought into the marina for people to have their pictures taken with them. Then what happens to these animals? A huge barracuda was brought in the other day...and I guarantee it wasn't eaten...just dragged through the water, photos taken...then dumped. I never hear much about it. Bottom line...I hate seeing five boats following a pod of dolphins...that's NOT a good thing. But it CAN be done responsibly. Just like I support strict regulation of trop collecting...but I don't necessarily think it has to be abolished completely...there are people out there who have been earning a living doing it for 30-40 years. Sorry for the rant.
