By reducing air pollution levels, countries can reduce the burden of disease caused by stroke, heart disease, lung cancer and respiratory diseases, notably asthma (World Health Organization, March 2014). These regulations can be found in the "WHO Air Quality Guidelines", which provide an assessment of the health effects of air pollution and thresholds for pollution levels harmful to health (World Health Organization, March 2014). Policies and investments supporting cleaner transport, energy-efficient housing, electricity generation and better waste management could reduce major sources of urban outdoor air pollution (World Health Organization, March 2014 ). These interventions can also help combat socio-economic inequalities and promote development. When societies have the opportunity to improve environmental quality, their overall health has the opportunity to improve. Even if the quality of the environment can sometimes be neglected, it nevertheless constitutes a very important public health problem. Living in an environment marked by mold, poor air quality and other pollutants can put people at high risk of chronic diseases. At each level of the SEM model, there is a possibility of negative effects due to poor environmental quality, but there are possible interventions that can improve these problems. In theory, societal intervention would be preferable
