Water pollution

Pollution in the world is a global problem that is affecting us today. There are campaigns to raise awareness of what is happening to the world and because of that i wanted to talk about this problem.

Water pollution, water incorporation of foreign matter such as microorganisms, chemicals, industrial waste and other types, or sewage. These substances impair water quality and make it useless for the intended uses.

The pollution problem arises now more sharply than in the past, for much of the waste have inorganic origin and are not attacked by bacteria disintegrating.

The effort to find a solution is hampered by population growth and the rapid industrial development.

Water pollution remains a problem as population growth continue to increase pressure on the environment. The infiltration of toxic waste in underground aquifers and saltwater intrusion in coastal aquifers of fresh water has not been interrupted.

The depletion of aquifers in many parts of the world and the growing demand for water will produce conflicts between the agricultural, industrial and domestic use of it. The shortage will impose restrictions on water use and increase the cost of consumption. Water could become the energy crisis of the early twenty-first century. Contamination of fresh and coastal waters, along with overfishing, has eroded to the point the fish fisheries resources would be necessary to close the fishery for a period of five to ten years for species to recover

Impact

Water pollution has affected human health.

The use of contaminated groundwater for drinking and cooking has led to health problems such as diarrhea, hepatitis, and occasional outbreaks of typhoid and cholera.

The inadequate water supply and poor sanitation cause more than 500,000 infant deaths a year as well as high levels of illness and disability in the region. In many countries, cholera is prevalent, especially in those where sanitation facilities are poor such as Afghanistan, China and India.

We need water and we do nothing to not pollutant!!
