Answer: Much is said about pollution and its risks to human health, however, many people have no access to the problem or problem that is aggravating. Many times, we are exposed to a large amount of smoke and do not realize that various diseases, such as cancer, are related to this excessive exposure.
Air pollution caused nearly seven million people to die in 2012. According to WHO, more than half of all deaths were due to so-called indoor or domestic pollution, which is characterized by the use of materials such as wood and charcoal for cooking. Although this habit seems far from the reality of many people, it is still quite common in poor areas.
