Salmon
are an important part of the PNW fishing industry and thus support the regional
economy. The people of the PNW, in turn, promote the ability of salmon to
thrive by preserving the shared resources of the Puget Sound, its waterways,
and lakes and rivers that are vital to the salmon life cycle. Commercial PNW
water life revolves around ensuring safe salmon migration and spawning by
keeping migration paths open and spawning grounds intact. Hatcheries even exist
for the sole purpose of hatching and raising young salmon through the dangerous
first stages of life!
With a relationship this strong and
co-dependant, both salmon and people alike are influenced by changes that
affect the other. Global climate change, a human consequence, is altering
environmental conditions in which organisms such as salmon live. The ability of
salmon to physically cope with these changes, namely in how they survive and
reproduce, will determine how their species populations and the linked PNW
fishing industry respond. If we are aware of changing climate conditions,
however, and can make predictions about their future status, as well as their
probable impact on salmon, we can do something with that knowledge. As PNW
residents sharing an environment with other vulnerable PNW natives, it is our
responsibility to organize a preemptive response to minimize and manage the
risk to an invaluable resource.
