Hello!!
Here is ur answer
Water pollution can be defined as alteration in physical,chemical or biological characteristics of water,making it unsuitable for designated use in its natural state.
WHO-world health organisation has defined water pollution as any foreign material either from natural or other sources that may contaminate the water supply and make it harmful to life.
Pollution of water leads to reduction of normal oxygen level of water, causes aesthetically unpalatable effects and spread of epidemic diseases.
It impacts the entire food chain and affects human health.
Freshwater bodies are polluted by domestic ,industrial and agricultural effluents.
Marine water bodies are polluted by oil spills, throwing of industrial and agricultural wastes and chemical particles in the ocean.
As a result of marine pollution all levels of oceanic life are affected and in worst cases dead zones are created.
HOPE THIS IS ENOUGH
