2. It's a trophic cascade...

The ocean run fish are keystone species, the forests and everything in them need them to return to spawning locations in order to stay healthy. The bodies of the fish feed the forest, without them the entire forest dies. We have this issue in the northern Rockies, it is one of the reasons the forests are teetering due to lack of ocean derived nutrients. The whole thing worked just fine until humans clogged up the rivers with dams.

The rivers in Maine were trashed by the paper industry and others, it was nasty, couldn't walk across the bridge over the river for the fumes, it was a shame. So to me, the fact that the rivers have recovered to where there are salmon runs is impressive and even more so that it happened in my lifetime.
