The pro-pollution argument is this - pollution is an unwanted environmental result of an otherwise desirable activity. Reducing pollution may mean curtailing the desirable activity (undesirable) or changing how the activity is performed to reduce the unwanted consequence. The second approach usually makes the activity more expensive and thus less desirable.

No one would argue that reducing pollution at a lower cost is a problem; that would benefit everyone. The problem is that pollution reduction is almost always a trade-off To understand the trade-offs you must understand the consequences and costs. The element that makes the whole situation intractable is that different people value the costs and benefits differently.

Sorry, this is a tough one.
