I have been teaching people to scuba dive with sharks for over 25 years. I can tell you for a fact that the shark population in the Atlantic is declining. It's pathetic. It makes me sick. Shark meat is excellent when eaten but for long liners to deliberately use equiptment that hooks sharks and kills them to be cast back into the sea as a by product of fishing for tuna is dispicable. Sharks are a necessary part of the ecosystem. Even I recognize that when I go scuba diving with sharks I am just visiting.
