What are the major causes of air pollution?

Air pollution has many causes. A big one is the factories that spit out toxins into the air. That, I believe is the worst one, especially those who deal with plastics of fossil fuel. The problem is mammoth and must be remedied. Factories get by with it because they are greedy and have the money to buy their way out of it.

If people would boycott their products, there would be more chance that they would change their wicked ways but it seems that people are either uneducated about the issue and don't know the specific companies they should avoid or else they are too lazy to do so.

If someone's favorite soda company is guilty of air pollution, few would give up their favorite drink. It is a sad day when people are not willing to take action and the failure to take action only makes the situation continue.

Many human activities contribute to air pollution. The most common activities are:
Combustion of fossils: Combustion of coal, petroleum and other fuels is known to be one of the major causes of air pollution. Combustion of fuel is common in industries and factories.

Emission from cars: Our vehicles use combustion to harness energy from fossil fuels. This process release pollutant such as carbon monoxide to the environment.

Aerosols and chlorofluorocarbons (CFC): CFC found in aerosols also affect the environment, it destroys the ozone layer.

Volcano eruptions: natural disasters can also cause air pollution, Volcanoes are known to release sulphur dioxide which is a pollution that can affect the air.

Other major causes of air pollution include: Forest fires, metal smelting, side effects from agriculture, and tobacco smoking.
