Quality of air is one among significant factors that affect public health. The air condition in a certain region has to meet certain level of purity to be considered healthy. Some indicators determine whether the air condition is qualified to make an area suitable to live in: level of oxygen and carbon dioxide, the existence of potentially hazardous particles, humidity, and so on. Nowadays problem that may cities face regarding the air quality is they are dealing with high levels of air pollution. Where do the pollutants come from?
To continue the discussion, there are several things we must pay attention to, if we talk about air pollution. The increasing rate of population is in line with the higher demand of everyday needs. From the basic to the tertiary, goods are produced by industries that involve some process including burning raw materials. The activities of either small businesses or large corporations exhaust particular chemical contents like carbon dioxide, carbon monoxide, sulfur dioxide, and others. Those molecules released to the air as pollutants because they bring no benefits for living tings and ecosystems. Instead, they are harmful if they enter respiratory system, cause several diseases like bronchitis and cancer, or even lead to death. Specific treatment need to be applied to every type of pollutant before they are released.
Another main source of air pollution is the higher level of burning coal to produce electricity, as well as the increasing level of vehicles using petroleum fuel. Both are consequences in addition to higher number of population rate.
Transformation of energy resources can be applied seriously to overcome this. The utilization of renewable resources such as solar power and bio-fuel can significantly help. The government can support by making regulation to boost the use of electric vehicles, for instance giving lower tax for eco-friendly ones. Overall, every part of societies must contribute to reduce air pollution.
