Air pollution refers to the presence of harmful particles in the air we breathe.
Primary sources of air pollution include:

1. Industries: industries produce a large amount of harmful gases like nitrogen oxides, sulphur dioxide through their large power plants directly into the atmosphere. When these air is inhaled by us it can cause hazardous diseases.

2. Vehicles: cars, bikes, trucks burn fuel and give out exhaust fumes which contain air pollutants like carbon monoxide, hydrocarbons and nitrogen oxides, when these pollutants are directly let into the atmosphere it causes air pollution.

3.Rural-household activites: In a few rural areas burning wood, coal, and other fuels for cooking is still encouraged. When these fuels are burned they emit harmful gases which cause air pollution.

4. Uncontrollable natural disasters: natural disasters like volcanic eruptions, dust storms release a lot of smoke & ash into the atmosphere which causes air pollution.

5. Chemical fertilizers used in agriculture: use of fertilizers and pesticides releases ammonia and other toxic chemicals directly into the air along with livestock farming which produces methane into the atmosphere which causes air pollution.

Air pollution can be reduced by the following ways:

1. Use of public transport: Adopting to use busses, trains and shared autos reduce the use of vehicles which produces harmful gases.

2.Saving energy: Turn off lights, appliances, and electronics when not in use. This reduces the demand for energy consumption, which in turn reduces the use of polluting power plants.

3. Recycle ♻️  and reuse: Reduce the use of newly produced materials by recycling the old materials like paper, glass, and plastic to reduce waste, which can create pollution.

4. Afforestation : Trees absorb carbon dioxide and other pollutants which is present in the air, helping to clean the atmosphere.

5.Usage of  eco-friendly products: Choose products with fewer or no harmful chemicals, such as natural cleaners and low-VOC paints to reduce the air pollution.

6. Support clean energy: Use renewable energy sources like wind, solar power, or hydro power instead of fossil fuels which emit harmful gases into the air.
