We all learn. Okay, not all of us. Kudos to those like you who do.I did the bull shark dive in Playa del Carmen, and regret it. For one, baiting the sharks just made it seem like an unnatural experience. The sharks circled around waiting to be fed. They reminded me of my dogs at feeding time. For me, it took something truly wild, and made into something more resembling a dog and pony show, or a circus act. Add a cage and its more so, one step closer to swimming with dolphins in a pen. Not to mention the negative impacts on the sharks. This is just my opinion.
I also saw a free swimming juvenile bull in Cancun, and that was much more impressive, as it was truly seeing a shark being a wild shark.
In my defense, I wasn't planning on doing a bull shark dive - I signed up for a regular dive, but the other diver came from Coz specifically to do a bull shark dive, so it was either go on the dive or scrap diving that morning. In the future, I will ensure that any diving I do does not feature baiting.
I realize that any diving I do will have environmental impacts, but I want to minimize them, and like you, I consider it selfish to bait. Just my opinion.
