Water is very important for the sustaining of living organisms. If no water is available then all lives will be vanished from the world completely. 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.
What Are the Causes of Water Pollution?
The first and foremost cause of water pollution is by human beings. Waste from household and from industries are dumped into the water resources. This will cause water to get polluted. Waste water from our sinks, showers, and toilets and from commercial, industrial, and agricultural activities can also cause pollution. Nutrient pollution, caused by excess nitrogen and phosphorus in water or air, is the number-one threat to water quality worldwide and can cause algal blooms, a toxic soup of blue-green algae that can be harmful to people and wildlife. Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea.
Effects of water pollution
Water pollution causes a very dangerous effect to the human beings and other living organisms as well. Waterborne pathogens, in the form of disease-causing bacteria and viruses from human and animal waste, are major causes. When water pollution causes an algal bloom in a lake or marine environment, the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water. This dearth of oxygen, known as eutrophication.
How to control pollution?
- Mainly reduce the usage of plastics and if using try to reuse the things.
- Stop burning plastic in soil that effect to the fertility of the soil.
- Avoid applying pesticides
- Dispose every thing at the right place.
- E waste should not be thrown in to the water siources.
