Sockeye, a species of wild salmon, are born in Kamchatkan waters and spend their entire life in the Pacific Ocean. Only once do they return to fresh waters - to spawn, start the cycle of life and to die. It is an inexhaustible resource that feeds billions of people on the planet, renewed every year! But soon, we may find ourselves facing the unimaginable: humans will exhaust the inexhaustible! (Ekofilm)
