This is the March 16, 2006, Bangladesh Women"s water supply sector in Dhaka hands outside the water to protest the shortage of water and air. This is January 11, 2006, near Garissa in Kenya, a mother and son in the road where the puddles of water. At present, the world is facing a water crisis.
Let us now look at the world"s population growth
This is a map of world population growth from the 1850s the world"s population reached 1 billion run in the 20th century, the world"s population is accelerating the growth of the total number of 150 years to 6000 million
Because of the substantial increase in population caused by the increased population density and urbanization increased. If the situation continues to worsen, According to UN research, 20% of the world"s population - 1.1 billion people - cannot drink clean water by 2050 at least 2 billion people in 48countries, and at most 7 billion people in 60 countries, will have serious trouble obtaining enough water. Now let us facie South Korea and China"s water shortage
Let us look at the per capita water resources of internationally recognized standards
<3000cubic meter mild dry
<2000cubic meter water at moderate level
<1000cubic meter for the severe water shortage
<500 cubic meter water to extreme
South Korea"s per capita is only 1488 cubic meters of water in the world among 153 countries in the first 130.
Although the total water resources in China total 2.8 trillion cubic meters, in Brazil, the former Soviet Union, Canada, after the United States and Indonesia is the sixth in the world. China"s large population, there is also a serious water shortage in the country, per capita is only 2400 cubic meters of water, some of the world"s average is only about 1 / 4 of section 109 in the world.
With China now the economic and social development, population increase and climate change and other reasons, a very serious situation of water resources, not only resources, water quality and increasing water scarcity, and the lakes, rivers, wetlands sharply reduced water pollution control and other ecological functions weakened. Forest Lawn-sik, the destruction of a reduced ability to conserve water. Wastewater emissions year-on-year rise, increasing the damage the water environment. As soon as possible if they do not take rigid measures, China will face catastrophic water crisis. China has taken measures to continuously enhance the sense of urgency, efforts to explore the potential of water resources, solid and effective in promoting water conservation, water management, water from the work of water resources and promote economic and social comprehensive, coordinated and sustainable development.
