David Attenborough goes scuba diving in Mediterranean. He talks about how Jacques Cousteau revolutionised diving in the 1940s by inventing the demand valve. Now people could explore the seabed and marvel at the wildlife there, such as fish, sea fans, coral, and anemones. But there was a downside - divers also hunted the fish and other creatures. Scuba divers go spear fishing and kill some small tropical fish.
