Very punny! But actually, you are correct...although it really doesn't solve the problem, it just disperses pollutants over a larger area.
Too much concentration of just about anything can be considered a pollutant these days! The so called pollutants come directly, or indirectly from the ground and even the ground it'self is considered a "pollutant" by militant GANG-GREEN when ANY erosion occurs... it's called TURBIDITY and according to them... MUST be eliminated!!!
In 1998, I attended a much ballyhooed conference attended by both Clinton and Bruce Babbit at Lake Tahoe about lake clarity. As usual, one could only submit questions on 3x5 cards in advance. It rained heavily that day and I submitted two and one was "I noticed on the way in here through the parking lots that a lot of ugly yellow stuff was being washed down the parking lot drains and into the lake! It appeared to be coming from our beautiful pine trees! What program does the Federal Government have in place to stop this detrimental substance from polluting the lake?"
The other question I submitted was, "Erosion is perceived as the prime cause of degradation in lake clarity. Since the time Lake Tahoe was formed, how does one explain how all the buildable level and semi-level land got into this basin and the lake remain as pristine as it has been?"
