Answers
Air pollution is a type of environmental pollution that affects the air and is usually caused by smoke or other harmful gases, mainly oxides of carbon, sulphur and nitrogen.
Many of the world's large cities today have polluted air or low air quality.[1]
Even 2,000 years ago, the Romans were complaining about the polluted air in their cities. At that time, the air was thick with smoke from fires and the smell of sewers.[1] Air pollution has been classified as a danger to human health and Earth's many ecosystems for a long time.
Air quality Edit.......
Pollution can be gas or liquid or solid. It can also be classified chemically, such as:- oxide, hydrocarbon, acid or other kinds. Pollution can also be classified by what makes it.
Many pollutants go into the air from natural sources. These pollutants include dust, sea salt, volcanic ashes and gases, smoke from forest fires, pollen, and many other materials.[1] In fact, there are many more natural pollutants than pollutants that humans make.[1] However, humans and other living things have adapted to most of these natural pollutants.[1]
