Beauty is hard to define but easy to recognise. In nature beauty may be discerned in all things and places, even in the most unexpected regions of the earth. There is beauty in the infinite variety of flowers, birds, animals and plants, many of which are vividly colourful.

There is beauty in mountains, valleys and hills, and in the skies. Then hunter who scans the forests for his quarry is often fascinated by the beauty that he finds in objects, which conceal beautiful flowers from human sight, suddenly reveal their secrets to him when he stumbles over them. The fisherman who turns to the sea for his livelihood is fascinated by the beauty of the multitudinous creatures that swarm in the seas. Many of these creatures are found even on the shore. But the oceans often conceal the beauty that lies below their surface, and to catch a glimpse of the beauty of the world below the sea, hundreds of divers everywhere explore the bottoms of the oceans, even at the risk of losing their lives in the unknown regions of the world below.
