Natural Causes of Air Pollution

Most of the pollution of the air is caused because of the ignorance and negligence of humans but it is also true that some time the air can be polluted by natural causes.

The natural factors causing air pollution are:

  1. Forest fires
  2. Wind erosion
  3. Radioactivity released from decay of rocks
  4. Volcanic eruptions.

Forest fires produce giant masses of smoke which tend to drift over nearby villages and cities.

Occasional eruptions of volcanoes can eject huge amount of volcanic ash and lava onto the earth surface which introduces dust and smoke into the atmosphere thereby polluting the air.

Natural air pollution can also be caused when rocks decay over time and release gas such as radon which has adverse effects on our health.
