Indoor air pollution has proved to be dangerous. As you travel to other countries, the smell of cooking fires fills the air especially in undeveloped countries. Different countries have distinct cooking smells. However, in a report written in October, it was shown that cooking fires kill over two million people per year. This number is greater than the deaths caused by malaria. Coal is the most toxic fuel we can use. However, wood, dried plants, dung, and other materials all give off soot and smoke that clog up the lungs. This can lead to chronic pulmonary disorders, respiratory insufficiency, and the list goes on. The World Health Organization said that “indoor air pollution greatly increases the risk of both chronic obstructive pulmonary disease and acute respiratory infections in children.” The acute respiratory infections are the number one cause of death in children under 5 in undeveloped countries. The toxins of these fires include carbon monoxide, polycyclic aromatic hydrocarbons, nitrogen dioxide, sulfur dioxide, and various airborne particles. In undeveloped countries, they purposely set off cooking fires sometimes because it treats the roof with soot, which help keeps insects away, and in some homes it is the only source of heat. Since most of these homes do not have proper ventilation, the toxins stay inside the home and cause major health problems.
