Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. The project includes the Global perspective, National perspective, possible scenarios and my personal views about this issue.
Water pollution today happens all over the world. Many major cities and countries form a part of it. The top five polluting countries are China, USA, Russia, India and Japan. The water and sanitation crisis claims more lives through disease than any war claims through guns. Some 6,000 children die every day from disease associated with lack of access to safe drinking water, inadequate sanitation and poor hygiene - equivalent to 20 aircrafts crashing every day.
According to UN statistics every day 2 million tons of human wastes are disposed of in water bodies. In developing countries, 70% of industrial wastes are dumped untreated into waters where they pollute the usable water supply.
The sources of water pollution throughout the world are,
· Fertilizers: Synthetic fertilizers can easily leech into lakes or rivers with the help of rainwater or excessive watering leading to water pollution. Fertilizers being drained into the rivers or lakes cause enrichment in nutrients and give rise to growth of algae. Projected increases in fertilizer use for food production and inn waste water
