About Air Pollution
Air pollution can have significant impacts on both human health and the environment.
The effects of air pollution vary depending on the type and concentration of pollutants, as well as the duration and frequency of exposure.
On human health, air pollution can cause respiratory problems, such as asthma, chronic bronchitis, and lung cancer.
It can also lead to cardiovascular diseases, stroke, and premature death.
The elderly, children, and people with pre-existing medical conditions are particularly vulnerable to the health effects of air pollution.
Air pollution also affects the environment, contributing to climate change and damaging ecosystems.
Acid rain, for example, can harm forests, lakes, and aquatic life. Ground-level ozone, which is formed by the reaction of pollutants in the atmosphere, can damage crops and reduce agricultural yields.
Air pollution can also contribute to global warming by trapping heat in the atmosphere and contributing to the greenhouse effect.
