Air pollution is a quality deterioration of the air that can be characterized by measures, pollutants chemical biological or physical presence in the air, with adverse consequences to the human health, living beings, climate, or material goods.

The leading causes of air pollution are related to the ignition of fossil fuels (coal, oil, and gas). The combustion of these raw materials occurs mainly during or in the operation of the industrial and sectors transport land.

Air pollution can have various short- and long-term effects on health. The pollution of urban air increases the risk of diseases acute respiratory(for example pneumonia) and chronic (lung cancer, for example) and also cardiovascular diseases. 

As the world gets hotter and more crowded, our engines continue to pump out dirty emissions, and half the world has no access to clean fuels or technologies (e.g. stoves, lamps), the very air we breathe is growing dangerously polluted: nine out of ten people now breathe polluted air, which kills 7 million people every year. The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt (World Health Organization, 2019). 

Finding solutions to air pollution is essential. Specifically on the side of road transport, it is necessary to develop soft traffic (pedestrian, rollerblading, bike ...), encourage sustainable mobility (established public transport network, develop parking at the entrance of cities, carpooling, car sharing ...), reduce the need for transportation at source (teleworking, walking, development of employer-wide travel plans). 

These solutions will help address the problem of air pollution and allow us to have a healthy environment.
