Flow

There are some things in our life we need so much like water, food and air. But the most important is the water because all things in our life contact from it. Because of that, all humans use it for agriculture, drinking, hygiene, extinguishing fires, providing drinking water and waste water services, industrial applications power generation and food processing so all things in the earth depend on the water and most of the earth is covered by water. http://chalk.richmond.edu/education/projects/webunits/water/waterimpt.html . In this report I’m going to write about the problem of Water pollution and the increasing needs of people for clean water.

There are many sources for water such as lakes, rivers, oceans and groundwater but if all sources are dirty, the humans will find problems and the need of water will increasing. In our lives, many countries have lack of water because some of them do not have source for water and they have water pollution. Water pollution is a major problem in the world. It causes deaths and diseases and it accounts for the deaths of more than 14,000 people daily. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day. Some 90% of China's cities suffer from some degree of water pollution and nearly 500 million people lack access to safe drinking water. In addition to the acute problems of water pollution in developing countries, industrialized countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres and 32 percent of assessed bay and estuarine square miles were classified as polluted. http://en.wikipedia.org/wiki/Water_pollution

This are some water contaminants like industrial waste and sewage. The industrial waste includes all materials resulting from the chemical industry. It’s so big problem in the water world and the other problem it’s about Sewage some of states are discharge the sewage in to water bodies like rivers, seas and lakes. From that behavior the water will be contaminants. Also that behavior it make so many diseases for the people in the world not only the people also for the fish in the water, also lead to reducing the oxygen in water and miss the fish and other aquatic. Dangerous diseases affecting humans by untreated sewage is :

• Brainerd ~ chronic diarrhea
• Dysentery ~ bloody diarrhea
• Cholera ~ dehydrating diarrhea
• Typhoid fever ~ prolonged abdominal cramps

The most common illness caused by swimming in contaminated water is gastroenteritis. Other types of contamination cause infections to develop on your skin, in an open wound and in your eyes, ears, nose and throat. Children and elderly are most likely to develop these water contamination related illnesses. http://www.healthblurbs.com/contaminated-water-disease-waterborne-diseases-contamination-of-water-diseases-causing-illnesses/

Generally, we must be careful about these diseases and we have to save water for a good future for us and for the next generation
