A pair of dolphins appear ahead of the sleek submarine as it cuts through the water, challenging the man-made object to a race.
The dolphins, good-natured as usual, don't seem offended by the intrusion on their natural habitat. They leap and frolic ahead of the submarine in what seems a welcome reception.
The speed and agility of the dolphins is impressive. They actually out-race the submarine which is capable of sustained high speeds, being powered by a nuclear reactor. The large amount of power that a nuclear reactor generates allows nuclear submarines to move at high speeds for long periods of time, unlike conventional submarines. The latest generation of submarines do not need to be refueled in their 25-year life span.
However, these adorable dolphins seem innocently unaware of the fact that the nuclear submarine, like most things man-made, is a threat to their natural habitat. Nuclear submarine radiation accidents are potential threat to the natural marine environment.
