"The natural life around the pond is irreversibly disrupted by the birth and development of an unusual baby beaver. His thirst for power leads to a remarkable transformation and a gradual disregard for the ways of the valley. As Ernest Beaver is able to do more work for his fellow beavers, they in turn are obliged to do more work for him, and Ernest's needs are enormous. Ernest's progress is a parallel to the industrial revolution, a revolution based on the energy multiplier. When man harnessed steam and electricity, gasoline and nuclear power, he could move thousands and then millions of pounds with the push of a button. With this new found ability to multiply his own energy, man could establish his dominion over all the nature" --Jacket.
