Whenever I think of air pollution, the first thing that enters my mind are greenhouse gases and the dangers associated with them. However, I rarely think of air pollution as something that can have immediate health impacts on people, which is why I found it interesting that the International Agency for Research on Cancer (IARC) stated that there were 223,000 deaths from lung cancer that were caused by air pollution. These were only deaths from lung cancer, but there is also evidence that increased air pollution can lead to bladder cancer as well as respiratory and heart disease. It is obvious something needs to be done to limit the loss of life that is associated with pollution.
Pollution is a negative externality because it is overproduced in relation to its social costs. It is clear that polluters are getting a free ride because they don’t have to pay the costs of these deaths. The market for pollution is not in equilibrium. We have not arrived at the socially optimal level of pollution because the polluters are not bearing the costs associated with their pollution.
This pollution is mostly happening in developing countries where industrializing is key for survival. However, we should not expect these developing countries to fix the problem on their own. Developing nations simply don't have the resources for pollution control, which is why developed countries have an obligation to assist these developing countries in their fight against pollution. The issue is not only limited to developing countries, the United States have done next to nothing to reduce their pollution levels, in comparison to other developed countries. The US is probably best equipped to handle their pollution issue, but negligence has taken over. If they wont take care of their own problems then it is far fetched to believe they will help out foreign countries.
The governments of the countries affected will need to get involved in pollution control in order to bring the market for pollution back into equilibrium. If they could convince the international world to to cooperate on some sort of emissions trading system it would improve their prospects. Producers in developing countries would need to buy the emission permits, while producers in developed countries would be able to sell them. They have better access to technology that help reduce emissions. It would be much easier to get help to developing countries if we had a better equipped international government, but since we only have the UN, developing countries are, sadly, on their own for now.
