Water is life. No creature, be it soiled or soulless. Can do without water even for a day. We need pure water for drinking. But it is a matter of grief. Man pollutes water. He throws waste into the water. He set up various mills and factories on the banks of rivers or canals. From these mills and factories, various chemical wastes fall into them. This falling of chemicals pollutes the pure water. Most of the chemicals used in mills and factories are poisonous.
They are, therefore, very dangerous; they pose a serious threat to our lives. Besides, many steamers, launches, and boats ply the waterways daily, and from them, human excreta and much more filth are thrown into the rivers and canals. As a result, water gets polluted. If water is polluted to such an extent every moment, the future is very dark.
