In the warm waters of the Coral Sea, a long and bitter battle is waged -the endless struggle for survival. Sometimes it's beautiful, like the shoals of silver pilchards: sometimes pathetic, like the defenceless baby turtles.
Into this pattern of inter-dependence has come man, equipped with aqua-lung and explosive harpoon, and an endless thirst for knowledge. So he snares the poisonous sea-snake to discover the secret of its venom: dynamites the shark that could kill him.

This film is the work of the outstanding Australian underwater photographer and director, Ben Cropp: it captures beauty in the frond of coral, action in the excitement of a shark hunt: and deals with a subject of ever-increasing importance - man's place in, and destruction of his environment.

In the dragon-shaped group of islands which is Japan, it is said that one is never out-of-sight of a mountain. These are the Japanese Alps, which run down through the main island of Honshu like a backbone. In this volcanic landscape hot springs, bubbling and boiling mud, and roaring vent-holes are all part of a sinister seismography. Snow blankets the peaks in winter, but in spring all kinds of wildlife come out of hibernation or up from the lowlands as the snows melt: Asiatic black bears, foxes, hares, flying squirrels, and a variety of birds.
