Some pollution sources are natural like forest fires that are started off by lightning or volcanism that sprays ash and debris in the air. The earth has its built in ways of getting rid of air pollution. However, man made pollution is rampant these days such as the pollution that is caused by burning fossil fuels.
Man made factors
The pervasive factors of air pollution are man-made. Petroleum products have been by far the most polluting products and the chief causes of pollution. This is especially prevalent in metropolitan areas. Pollution can be caused by fuel combustion as well. Hydrocarbons like gasoline and their burning also leads to production of pollutants like water vapor and carbon dioxide. In order to reduce the pollutants in the air one often uses dehumidifier Sydney.
There are different kinds of air pollutants like carbon monoxide and carbon dioxide. Fossil fuels are not pure and engines cannot be as efficient that there will not be any small amount of soot that is released. Again, smoke from power plants as well as factories also cause pollution and this also leads to acid rain. For homes and closed spaces, in order to reduce the air pollutants in the air, one can use a dehumidifier.

Though it is man-made pollution that is talked about the most, natural sources can be equally dangerous. Wind erosion leads to dust, which then swirls in the air and causes pollution. Livestock release methane, which also circulates in the air. Again, smoke from wildfires as well as volcanic eruptions can cause different kinds of air pollutants to be present in the air. These consist of substances and chemicals like sulfur, chlorine and others which can be abrasive and this can cause harm to the health of animals and mankind.
Direct and indirect effects
There are direct as well as indirect effects of air pollution that society needs to guard against. The swirling dust particles in the air cause varieties of lung diseases. The same goes for the smoke and fumes that are erupted from cars and other vehicles. The indirect effects are the toxins that get into the systems of man and animals and lead to different kinds of ailments. The respiratory system is acutely affected by high levels of air pollution. Many cities and urban areas struggle to deal with these problems. One of the steps being taken is to increase greenery in such areas so that the harmful gases can be reduced to a certain extent by the presence of trees and plants.
