How does this affect me?

Marine water quality, freshwater quality and the quality and conditions of our lands are the touchstones to both our history and legacy for the future. The quality of the marine environment affects everything from the quality of the food you put on your table, our economy, and the quality of our community life. Our marine waters contain an abundant array of animals and plants that are interconnected in almost limitless ways.

Marine water quality is affected by what humans do near the water, such as wetlands, beaches and the general areas where our land meets the water we love.

When stratification isolates the surface water from the deep water, the following effects can be seen:

Fish Kills from Low Dissolved Oxygen

In addition, human additions of nutrients (e.g. sewage input, agricultural and domestic fertilizers) can cause increased algal growth that ultimately can result in lower oxygen. Thus, human additions in strong-persistent waters have consequences that are not realized in well-mixed waters. See the Hood Canal Dissolved Oxygen Program for detailed information about trends in low dissolved oxygen in Hood Canal, Puget Sound.16

Concentration of Pollutants

Stratification can result in the retention of pollutants and contaminants in surface waters, where much of the plankton (including sensitive eggs and larvae) is concentrated, instead of mixing and diluting these out and away from the surface zone.

Impairs Water as a Carbon Sink

By protecting marine habitat we also preserve the marine environment's ability to serve human needs. Estuaries like the Puget Sound Georgia Basin act as sinks, or sponges, for carbon dioxide formed by burning petroleum (energy, vehicles, manufacturing). If temperatures rise too dramatically, the ability of these waters to act as sponges is greatly reduced and this, in turn, affects the production of basic food sources in the marine environment. These primary producers include phytoplankton, macroalgae, seaweeds, kelp, seagrasses and tidal marshes. These producers are food sources for other marine fish and animals.17

Loss of Watchable Wildlife Revenues

This region is one of the most popular in North America for Watchable Wildlife. Where human-caused pollution contributes to areas with strong-persistent stratification, this can contribute to negative affects on the production and diversity of marine life. As a result, particularly with respect to fish kills, tourism and licensing revenues are affected. In Washington State alone over $980 million is spent annually on viewing wildlife. Money is spent on lodging and food, and on supplies such as boat rentals, cameras, binoculars, spotting scopes, books/maps, tents, packs, and membership dues. In Hood Canal, SCUBA divers are among the highest "viewing" spenders – up to $3,000 in gear, $150 for lessons and $150 for other related expenses.

The revenue stream is simply astounding. On average, since 2001, over $1.7 billion was spent on wildlife viewing activities, creating 21,000 jobs in the state, $426.9 million in job income and $56.9 million in state tax revenues each year.18

Failed Legacy and Investment in our Children

In the face of a growing population, we have no choice but to manage growth in the most sensible way that preserves species, habitat and quality of life for the future.

What will we tell our children when we allow species to go extinct or become severely depleted when we had economically viable options to protect them?
