Environmental Threats

Growth of the human population in Western Washington brings with it increased pressures on the system from development, release of damaging chemicals into the air and water, and over-exploitation of natural resources. These pressures have associated stressors such as fragmentation of habitats, toxicity, and reduction in resilience of native species. Climate change represents a clear stressor as illustrated by increased acidity of the water.  Warmer water will affect the viability of the native species and associated food web. Increased inorganic nutrients are already showing impacts in harmful algae blooms. Overharvesting of salmon is perhaps the leading reason for declines in Orca. Derelict fishing gear kills massive numbers of fish and crabs. Weakening laws such as the Clean Water Act potentially could turn back significant progress that has been made since the early 1970’s. 

Cultural Issues

There is a lot to learn from the Coast Salish Tribes about sustainability, and the overall approach to the system and the resources. Everyone should understand that human well-being is linked to a heathy ecosystem, of which the Salish Sea is a major element.

Stewardship

Support actions that reliably result in a measurable cumulative net improvement to the ecosystem. Think of reducing one’s effect through sustainability, reducing fragmentation, and supporting responsible science-based restoration and conservation programs.
