Over two thirds of Earth's surface is covered by water; less than a third is taken up by land. As Earth's population continues to develop, people are putting stress on the planet's water resources. In our oceans, rivers, and other inland waters are being "compressed" by human activities. Poorer water quality means water pollution, it means one or more substances have built up in water to such an extent that they cause problems for animals or people, there are many causes in our world that needs to be fixed in Health care or else the human world will be in chaos, which extinction will occur to animals and diseases will spread to human beings that cannot be cured.40% of water got polluted and the death rate in the human civilization will keep increasing until extinction will occur. The effects of water pollution are varied. They include poisonous drinking water, poisonous food animals, unbalanced river and lake ecosystems that can no longer support full biological variety, increasing acid rain, and many other effects. Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants.
There are many causes in water pollution in our world. The world is facing water pollution and on its surface and ground water resources from agricultural, domestic and industrial services. Agriculture is a main provider to water pollution. Drainage water, seeps from undeveloped fields, although considered as a nonpoint source of pollution, this Drainage water is collected and concentrated in undeveloped drains to become a Source of pollution for Niles and Lakes, Drainage water could become also a source of pollution of groundwater. Major pollutants in agricultural drains are salts, nutrients (Phosphorus and nitrogen), pesticide residues (from irrigated fields), and pathogens (from domestic waste water). Drains also receive untreated domestic and industrial waste water which are sources of toxic organic and inorganic pollutants.
Homes and businesses produce public solid waste as a result of everyday
actions. Organic waste constitutes about 60% of public solid waste, paper averages
11%, and glass, plastic, textiles, bones and metal, Of the 15 million tons of municipal solid waste generated annually, about 65% is in urban areas and the rest are from rural areas. Waste collection efficiency ranges from 90%in high-income areas to 10% in rural low-income areas where solid waste is dumped in government-designated sites or in adjacent land where it putrefies and self-ignites. Waste is also sometimes burned or disposed into undeveloped drains and irrigation canals, thus significantly corrupting water quality and increasing health problems.
Another major cause resulting water pollution is Fast urbanization and industrialization resulting
In discharge of untreated or partially treated wastewater, joined with massive abstraction of water for irrigation, industrial...
