there is a garbage problem throughout the state and country. i think the non-litterers are a tiny minority with the amount i see everywhere along not only the roads, but trails and rivers. as for the garbage being the pollution harming fish, it is possible but there are far worse pollutants being dumped all over and draining into puget sound (marine survival being the main problem right now for puget sound steelhead). with the amount of chemicals pouring into puget sound from our yards, farms, and pavement and the many new chemicals coming out all the time... it wouldn't surprise me if this toxic stew is having impacts far beyond what we now know. you can only stretch a rubber band so far before it breaks. our fish populations are possibly at that breaking point after centuries of intensively destroying everything wild fish rely on.
