- Factories and furnaces may add to air pollution.
- Different nuclear tests create radiation.
- Thermal power plants also pollute the air.
- Pesticides also increase pollution.
Water Pollution:
Water pollution reduces the amount of pure freshwater that is available for drinking and cleaning. It is also important for swimming and fishing. Water maintains 70% of the human body weight.
