Pollution is the action of increasing pollutants in the natural environment that cause adverse effects on our natural ecosystem.
Historians have documented signs of air pollution at least 2400 years ago in Greece. In Europe, diseases such as cholera and typhoid fever spread rapidly during the middle ages due to pollution.
After the Industrial Revolution, the number of factories increased rapidly across the world. Chemicals and fuels used in factories resulted in increased air and water pollution.
Untreated polluted air containing carbon dioxide, Sulphur dioxide and carbon monoxide released from factories into the air contributes to air pollution.
Untreated industrial waste contains chemicals and heavy metals that are potential pollutants and are often disposed of in nearby water bodies, contributing to water pollution.
Yamuna is one of the most polluted rivers in the world due to water pollution contributed by industrial waste. 58% of the waste of Delhi city is dumped in this river.
Water from polluted rivers such as Yamuna is a major source of irrigation water and other household purposes. But due to pollution, it is impacting the lives of millions of people.
We can already observe the effect of pollution on our environment, due to global warming, average global temperatures have increased by about 1 degrees Celsius since 1880.
