Burning Fossil Fuels
The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere.
What are the 5 main causes of air pollution?
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.

What is pollution Short answer?
Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
What are the 10 effects of pollution?
Loss of soil nutrients, which renders the soil unfit for agriculture. Impacts the natural flora and fauna residing in the soil. Degrades vegetation due to the increase of salinity of the soil. Toxic dust (such as silica dust) can cause respiratory problems or even lung cancer.

Why is it important to stop air pollution?
Reducing pollutants in the air is important for human health and the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants can also damage plants and buildings, and smoke or haze can reduce visibility.
Where does pollution happen?
mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.
What was the first air pollution?
The first major change from routine pre-industrial air pollution came in England with increased use of “sea coal” in the 13th and 14th centuries. (It was called “sea coal” because it came by ship from northern cities like New Castle).
