Every year, unsafe water sickens about 1 billion people. And low-income communities are disproportionately at risk because their homes are often closest to the most polluting industries.

This dearth of oxygen, known as  eutrophication , suffocates plants and animals and can create “ dead zones ,” where waters are essentially devoid of life.

Water pollution occurs when harmful substances often chemicals or microorganisms contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.  Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution. In fact water pollution is created by us ( humans). And it is one of the most and critical environmental problems of the planet Earth. It involves in the destruction of it. One day we could get rid of clean water or even water itself. SOURCE:  https://www.nrdc.org/stories/water-pollution-everything-you-need-know
