What is Air Pollution?
The Earth is bounded by a shield of air (made up of various gases) called the atmosphere. Without the atmosphere, we will be exposed to intense heat by day and frozen by low temperature at night. Life on earth is made possible because of the atmosphere.
When gas, dust particles, fumes (or smoke) are introduced into the atmosphere, they cause air pollution. This is harmful to humans, animals and plants because the air turns out to be dirty (contaminated or unclean).
Any other gas, particle or odors that distort the natural balance of the atmosphere and cause harm to living things can be called air pollutants.
