Air pollution in many parts of the world is very serious. Nine out of ten people around the world breathe polluted air, and seven million people die each year from air pollution. Up to a third of deaths from stroke, lung cancer and heart disease are caused by air pollution.
How air pollution affects our health?
According to the World Health Organization (WHO), about 92% of the world’s population lives in areas where air pollution levels exceed the limits. The air pollution was responsible for 6.5 million deaths in 2012, accounting for 11.6 percent of global deaths that year.
The potential health effects of air pollution range from subtle physical changes in the body to obvious symptoms such as
- itchy nose and throat
- chest pain or tightness
- Exposure to air pollutants exacerbates asthma or chronic respiratory problems.
What causes air pollution？
Air pollution sources can be divided into two categories, Natural factor and Human factor.
Natural factor: many different pollutants and chemicals form and emanate from natural processes in the earth’s crust. For example, volcanic eruptions and forest fires.
Human factor: It is the main aspect of air pollution, which is mainly generated from people’s production activities and daily activities, such as industry, transportation, various combustion and waste disposal.
How to solve the problem？
- could tighten controls on illegal incineration of garbage or forests. For example, increasing fines
- can give some speech about air pollution to the people, let them know how to protect the environment and increase the public’s awareness of air pollution.
- People cultivate the use of public transportation, which can reduce air pollution.
