Puget Sound orcas are majestic mammals. They are the largest species of dolphin on the planet. Living in matriarchal family groups with the lifespan of females in the 80's and males in the 70's. But, due to pollution, dams, boats, and the navy, the orcas' lives are on the edge. The pollution in Puget Sound is soo bad that when an orca dies and washes up on shore its body is consider toxic waste and is treated as such. The main toxin is PCB. The toxins are passed down from mother to calf through nursing. Pollution comes from agriculture runoff, industries, sewage, etc.. Anything that goes down a drain in a Western Washingtonian's house or on their streets ends up in Puget Sound. Also, dams contribute to the orcas' decline. Damming up rivers and streams means less salmon are migrating meaning less food for the orcas. With the decrease in salmon, orcas must look harder to find fewer fish. But, this becomes even more difficult with noisy boats in the water. Navy sonar doesn't help orcas or any marine life either. It causes loss of hearing, messes up the orcas' navigation causing mass stranding on beaches, the list goes on.
The Native Americans see the orca as relatives. The orcas are humans who were transformed when trying to communicate with their previous human families ashore. The orcas are also seen as the reincarnation of chiefs as in the case of Luna.
