Karuk Tribal members' health is declining because the Klamath River salmon that used to make up most of their diet are declining, says a Washington Post article published yesterday. The salmon that once amply supported the Tribe are now an endangered species, blocked from their habitat by dams and diseased or killed by poor water quality on their seasonal runs. According to a University of California study, the lack of fresh salmon in the Tribe's diet - and replacement of other sources of nutrition - have harmed the health of Tribal members.
