The water which we can use has only 25% among all water in the face of the Earth. Though the water is an important resource, in late years pollution advances. We call this water pollution and bring it into question. Water pollution is that the ocean, a river, a lake, well water, tap water is polluted by various factors. We tend to think the cause of the dirt of the sea and the river to be the drainage from a factory and the farm, but 60% of causes of the pollution are life drainage appearing from the house. However, it is the present conditions that there are few people understanding for water pollution. Therefore we are interested about more water pollution, and it is necessary to understand.
Effects
Water pollution causes problems. First, water pollution is very harmful to humans. We drink water that comes from a source, a lake or local rivers. In countries that have poor facilities which makes clean water
, there is always outbreak of cholera and diseases as because of poor drinking water treatment from contaminated water. We are also affected by water pollution by eating seafood that comes from contaminated sea.

Solution abroad
It is so awful that Current situation of water pollution in China. Agricultural water from rivers and lakes contain the chemical fertilizer. Chinese authorities says that Groundwater of 97% across the country is contaminated and Pollution of urban groundwater of about 64% is very serious. So China worried about drinkable water paucity. Chinese government is trying to solve the problem in order to respond to energy, agriculture and other demand. For example, this is one method that shed a large amount of water from clean river to contaminated river. And this is also one method that dredging of bottom sediment is one of the most important ways to improve the water quality.
Conclusion and Our Solution
It is limited in the world. So water is very important. It is said that many people dead around the world every day because of water problem. Water problem is seriousness.
To solve water pollution problems, we suggest solutions. It should resolve time and money chemical water pollution. But river pollution of domestic wastewater is different method. We use in an appropriate amount of detergent and water. We provide clean water and environment to get water to people in developing countries. Finally world people use water to important.
