In essence, the level of pollution is determined by a series of cost-benefit analyses. There are three major avenues to reducing pollution. We can use voluntary measures, direct controls, or market incentives. Each of these is explained below. Obviously, noone wants pollution.
Pollution occurs as a by-product of some other activity.
Pollution is undesirable, but also unavoidable. The answer is no. Market forces, if left to themselves, generate too much pollution. The reason for this is that pollution is a negative externality. An activity generates a negative externality when the activity imposes unwanted costs on an uninvolved party, and those who bear the costs are not compensated by those responsible.
