Expeditions with Patrick McMillan: The Great Bear Rainforest (pt. 2) - A Biological Perpetual Motion Machine
Air Date: May 10, 2009

Most people know the story of salmon, they run up stream, lay their eggs, then die...but do you know the rest of the story. It turns out that the dead salmon are one of the most important links that tie together the intricate flow of nutrients, and thus life, here in the rainforest ecosystem. Join Patrick as he travels with Heiltsuk First Nations members up the rivers with the salmon, eagles, and bears, to the very peak of the mountains following the flow of nutrients from ocean to the forest as he uncovers the amazing story of a biological perpetual motion machine, a system that today, is threatened by a changing world.
