11 Causes of COPD

5. Harm caused by air pollution

Studies have shown that polluted city environments also expose citizens to increased COPD risks. The pollution may come from factories, but quite often it is caused by the fumes of all those car exhausts. In this regard, people of lower socio-economic status are more likely to develop this disease than others because their lack of means forces them to live in inner-city areas where they are closer to the primary sources of pollution.
