- Commentator: It has been established beyond all reasonable doubt that the great Arctic change of climates started somewhere about 1900 and has spread so rapidly that small glaciers have already disappeared, and the big ones are melting at a startling rate.
- Commentator: The oceans of the world are responsible for many things, some good, some bad. Very possibly the most interesting of all is the proof that the sea dominates the world's climate.
- Commentator: Tracking the sea's elusive answers through the great white waste is among the most difficult of all scientific adventures. The men who seek the secrets of the seas of the Arctic are a special breed of hero. By ship, on foot, by dog team, they hunt the key to the world's climate.
- Commentator: There is a theory so startling and so scientifically documented that all the world might well take notice. The theory is that here in the Arctic waste, buried beneath a billion tons of frozen sea, hides an astonishing secret. If all the ice in all the world continues to melt, the levels of all the seas will rise 100 feet or more and the great coastal cities of all the world might well be drowned.
- Commentator: Man, with all the science of the past at his command, now knows the melting of all these glaciers, coupled with the drastic upheaval of the land masses of the globe, might one day drown more than half the Earth.

- Commentator: What is the fate of the world? Is this the end?
- Commentator: [a shark is shown being baited, hooked, hauled aboard a boat at sea] Off the Florida coast, sharks are often trapped by this method of doped, baited hooks, which causes them to temporarily lapse into unconsciousness, until such time as they can be brought to shore and dumped into gigantic tanks at Marineland, for public showing.
- Commentator: [the tank with shark and shark-walker is shown] Once they're dropped into the tanks, the job of reviving them is turned over to a shark-walker. By keeping them in constant motion, despite their unconscious state, oxygen is forced through their gills and they are gradually revived.
- Commentator: [shark-walker is seen working closely with a shark to help revive it] The occupation of shark-walker is not overpopulated. There are no statistics available, but it would seem likely that walking a shark was one of the less-popular outdoor sports. When that shark starts breathing properly, the man directing underwater traffic will suddenly sprout wings. The shark is expected to show no gratitude for being revived, and seldom does.
