All we do now to save salmon could mean nothing | McClatchy: "BOISE, Idaho -- The Pacific Northwest has spent two decades retooling dams, rebuilding damaged watersheds and restoring stream flows to keep salmon from disappearing.

The United States has invested billions in the effort - $350 million in 2004 alone - by far the most money spent on any endangered species.

But a new threat is more devastating than the gill nets that sent dozens of salmon runs into extinction. It is more deadly than the hydroelectric turbines that still kill millions of migrating smolts. In fact, it raises doubts about whether salmon will survive in the Northern Pacific at all."
