Saving the orcas
Scientists say that food is the most immediate need for the Southern Resident killer whales. This week we are going to learn about Chinook Salmon - why they're also struggling to survive and what's being done to help them. We are starting our journey on the Skagit River, which is one of Puget Sound's most important rivers if we want there to be a future for Chinook Salmon, and the killer whales who depend on them.
