How do humans affect water pollution?

How do humans affect water pollution?

Agriculture is also the main source of pollution in rivers and streams in the U.S. One way that agriculture causes water pollution is through rainwater. When it rains, pollutants, such as fertilizers, animal waste, and pesticides get washed from farms into waterways, contaminating the water.

What is the importance of drinking water?

Drinking Water Helps Maintain the Balance of Body Fluids. Your body is composed of about 60% water. The functions of these bodily fluids include digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature.

Such pollution is a major source of death and disease worldwide, especially in developing nations.

What is water pollution in simple words?

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.
