Aerosol sprays
Paint fumes
Oil refineries
City pollution
Mobile Air Pollution
Trains
Cars
Planes
Motorcycles
Natural Pollution
Windblown dust and sandstorms
Pollen
Fog and smog
Volcanic ash from eruptions
Three Types of Air Pollution
Earth's ozone layer starts to thin
Polluted air contaminates the oxygen of the environment
Puts too much CO2 in the atmosphere
The issue of polluted air could fade away in time if we change our economy and lifestyle.
Chlorofluorocarbons (CFCs) have a stronger effect on the ozone, so by ending use will help ozone layer repair itself
It more depends on the people and their choices
Walk instead of drive
Carpool
Ride the bus
Reduce, reuse, and recycle
Use energy saving appliances
Don't burn garbage
