What is the biggest source of air pollution?
There are four main types of air pollution sources:
- 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.
What is the biggest cause of pollution in the world?
Closer look at the activities that cause air pollution include:
- Emissions From Industrial Plants and Manufacturing Activities.
- Combustion From Fossil Fuels.
- Farming Chemicals and Household Products.
- Natural Causes of Air Pollution.
- Other Causes.
What causes the worst pollution?
Because a large share of air pollution is caused by combustion of fossil fuels such as coal and oil, the reduction of these fuels can reduce air pollution drastically. Most effective is the switch to clean power sources such as wind power, solar power, hydro power which don’t cause air pollution.

How long has air pollution been happening?
Before the Industrial Revolution, our planet’s atmosphere was still untainted by human-made pollutants. At least, that’s what scientists thought until recently, when bubbles trapped in Greenland’s ice revealed that we began emitting greenhouse gases at least 2,000 years ago.
Why do people pollute?
Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water.
What are the 4 types of pollution?
