One of the world’s most increasingly popular recreational activities on holiday is SCUBA diving. People as young as 10 years old and as old as their health will allow can breath pressurized air from a tank at depths of 12 metres or more, while swimming alongside marine life such as clown anemone fish, moray eels, turtles, sting rays and even sharks. Such has been the acceptance of exploring this alien world for humans that it has become a huge tourist earner for countries all over the world.
