Marine mammals outdueling fisherman for salmon, and it's a problem for orcas

Marine mammal populations have been rebounding along the West Coast in recent decades, and apparently they're eating a lot to celebrate.

According to a new study, marine mammals, such as orcas, sea lions and harbor seals, up and down the West Coast may now be eating more Chinook salmon than those being caught by commercial and recreational fisheries combined.
