The North Pacific Ocean and the Salish Sea have been home to an abundance of fish and other aquatic life since long before humans walked on our shores. Now, though, due to human-caused climate change, those waters are quickly heating up, becoming more acidic and more bereft of oxygen. If those trends continue, a day may come when there will be little more than jelly fish surviving in Puget Sound.

The coastal waters of California used to be busy with the traffic of salmon and orcas. No more. The sea has gotten too warm. The same phenomenon may be happening in Washington, where orca pods are stressed and salmon are fewer and smaller.

We are already concerned about the smoke from more frequent wildfires polluting our air and a shorter snow season ruining skiing in the Cascades, but our biggest worry may be what’s happening underwater, where we can’t see the looming calamity.
