  Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times.Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA).Since then the sport of SCUBA diving has gone from strength to strength.

  Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive.SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(动、植物).Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.

  SCUBA diving is not without its dangers, however.The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’.Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water.Diving can also be harmful to the underwater environment.However with proper precautions diving can open up a whole new world, far from the stresses of daily life.
