In answer to your question, it will only end when our appetite as consumers for things made from petro-chemical based products is subdued. Personally I hate the BP spill as much as anybody...I have fished those waters many times and hate the thought that they are being polluted. I just can't bring myself to vilify "Big Oil" when I enjoy getting in my truck, driving 150 miles to a river (and use the requisite gasoline), put on my waders, boots, high tech rainwear (all made from petro-resin derived matterials), get out my fly rod (made with HIGHLY refined Resins), string up my fancy flyline (you guessed it, more resin), loop on a leader (yup....more resins), just to stand in a river to try to catch a fish I won't even eat. All of this supposes that I don't take one of the boats. In the end, if we didn't DEMAND products that start with oil then "Big Oil" would not have all those "insane, immoral" profits to reap. We have this problem because WE asked for it. Period. Until we are willing to remove the plank from our own eye we ought to refrain from picking the splinter from anothers'.
