Mills and factories discharge very harmful waste waters into many rivers and sea.
The water of the Ganges flowing by the side of both Varanashi and Calcutta is extremely polluted and contains all sorts of dangerous bacteria.
It takes place when effluents from factories are let into rivers.
When there is no river the effluents from the factories stagnate on land.
Thousands of the residents of Bhopal died due to lungs problem which was caused by methylamine gas from the Union Carbide Plant.
The glaring incident is the Bhopal gas leak in December 1984.The abundance of water on planet earth doesn’t make it unlimited and inexhaustible.Quantitatively freshwater constitutes only 1% of the entire water resource present, and most of that too is locked in the ice-caps and glaciers.We have also I minister to look after the environment.Water is equal to life for every living thing, be it humans, animals, birds or trees. But what will happen if there is no water for us to drink?It is really very strange and laughable that large number of the Indians regard this water as holy. There is no doubt that the fish that grow in such waters are poisonous too.Reckless application of chemical fertilizers, insecticides and pesticides pollutes the soil.It is mainly caused by toxic chemicals and biological agents which change the chemical composition of water significantly making it unfit for human consumption and usage.It poses harm to both human health and environment.The evils of sound pollution can be imagined from this example.The water of rivers and seas is being constantly polluted all over the world by various dangerous chemical and biological wastes.
