"The salmon runs are a visible symbol of life, death and regeneration, plain for all to see and share... The salmon are a test of a healthy environment, a lesson in environmental needs. Their abundant presence on the spawning beds is a lesson of hope, of deep importance for the future of man. If there is ever a time when the salmon no longer return, man will know he has failed again and moved one stage nearer to his own final disappearance."
