Air pollution can be broadly defined as the presence in the air of any substance that can affect our health or the health of plants and animals or causes damages to property and to our environment. These substances are in large part emitted by human activities but can also have natural origins. They are at the source of well known environmental issues such as smog and acid rain. Some also rise to the atmosphere above us to affect the ozone layer or to contribute to climate change. Air pollution can also affect indoor air quality.
