The Mackenzie and Amazon valleys are 10 000 km apart and are ecologically distinct. Yet, in a subtle sense they are collaborating elements within the biosphere, the Earth's thin layer of living matter. In this film are seen two of the world's myriad river ecosystems and how they are linked within the biosphere.
