Description The discovery of vast shoals of fish in the Pacific Ocean off the coast of Peru has led to the development of a large industry which processes fish meal for use as cattlefeed and fertilizer. However, the vigorous exploitation of this resource has done its damage; a whole species of fish, the anchoveta, is in danger of extinction because of overfishing. Further, little of the protein being won from the sea is being used to improve the diet of people in South America, who need it badly. The film shows how market demands in one country can damage the environment thousands of miles away.
