Environmental pollution refers to the introduction of harmful pollutants into the environment. The major types of environmental pollution are air pollution, water pollution, noise pollution, thermal pollution, soil pollution and light pollution. Deforestation and hazardous gaseous emissions also leads to environmental pollution.

Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity. Pollution from natural occurrences is not very often. Human activities that result in air pollution include: 1. Emissions from industries and manufacturing activities.
