Every year huge numbers of salmon return to the river systems on the Alaska Peninsula to spawn, and by doing so they bring essential nutrients from the ocean to the land. The fish feed the bears, and the bears feed the forests - by dragging half-eaten salmon carcasses into the forest, and by depositing nitrogen in the form of scat and urine. Closing this perfect ecological circle is the fact that the healthy trees then provide shade necessary to keep water temperatures low enough for salmon. Just watching this video memory gives me goosebumps - I'm never happier than when in places like this."
