Water is so important, but now, the world must still face the risk of water shortage and water pollution are serious. Pollution of water resources, lack of clean water increases the risk of intestinal diseases, skin diseases and some diseases khac.Trung average about 1.5 million children die from diarrhea each year . According to WHO estimates that up to now has about 130 million people are faced with the use of contaminated water with arsenic concentrations above the allowed concentration of 10 mg / liter. Therefore, the role of water for life important and necessary than ever.
The issue of water and human life - Water & Health
Source of water for domestic increasingly polluted and depleted
The demand for water for domestic, industrial and agricultural production is growing strongly along with the socio-economic development and population explosion. According to the results of the evaluation in 1999, 8.8% of the total annual flow frequency corresponding to 75% of the total amount of water needed by the country. This figure increased to 12.5% in 2000 and 16.5% in 2010. 41 km3 (accounting for 89.8%) in 1985, up 46.9 km3 (1990) and 60 km3 in 2000 ( 85%) is the total amount of water used to irrigate crops, this figure accounts for a high percentage. The amount of water used for agriculture in the dry season is very large. The total amount of water used in the dry season of 2000 reached 70.7 km3, accounting for 42.4% of the total water supply capacity in the dry season, or 51% of the dry season flow corresponding to the frequency of 75 %.
In many areas and river basins, water can be used several times the total amount of water can be provided, meaning that not only far exceeds the threshold amount of water required to maintain ecological but also no water at place to provide for living and production.
As mentioned above, the increase in population and human activities will increasingly strong impact to the natural environment in general and in particular the aquatic environment.
The vast green forest in Truong Son, Highlands, northern mountains are cleared to leave the mountains, barren, gray, farming and forestry irrational and indiscriminate waste into the waters ... has and will cause very serious consequences, making depleted water resources, pollution and drought likely more intense. The risk of water shortage is exacerbated, especially in the dry season in areas of low rainfall.
Fresh water is a renewable resource, but the use of these resources must be balanced between stocks and renewable. That was how people should care about, made to survive and develop life-stable, durable.
We also save green forest and water resources of us? We have the ability if we knew each startled, stopped, started again. Now to end all mining activities rampant, destroying the remaining forests. Reforestation, restoration of green for the forests. In order to hundred years later, our children can palm a handful to sip cool water pure, tasty drink stock back on every river, creek. For the life was saved, proliferation, development and longevity.
