As with most things in life there is an associated risk! We need to stop and think and then be free to decide for ourselves if that risk is worth it! No one, and I mean no one should be made to go on a shark dive! The benefit is to the local economy for sure, but the bigger benefit is to the understanding of the fish and that fish as a sustainable resource! Many third world counties never thought of their reef systems that way until the dive industry moved in and showed the local government that it was better to bring tourist dollars into the country than fish the reef out and see it's destruction! Risk assessment in life is front line for man to expand his world and has always been their even when the Vikings set sail for the new world! I am glade all explorers understand this concept!
