1.1 billion people worldwide currently lack access to safe drinking water, according to a report by the United Nations Environment Programme. The problem of water pollution has become a global problem, which seriously threatens human health and development. Especially in developing countries, drinking water safety issues are more prominent.
In recent years, whether in developing or developed countries, the issue of drinking water safety has repeatedly touched people’s fragile nerves. This problem has gradually become a global challenge.
In December 2007, the United Nations Environment Programme released a report that 1.1 billion people worldwide do not have access to safe drinking water, a problem that may be exacerbated by climate change and population growth. The UN even warns that if the world’s population continues to increase, by 2025, one-third of the world’s population will have to worry about obtaining safe drinking water.
Compared with developed countries, drinking water safety is a worrying issue in developing countries due to poor infrastructure. UNESCO recently released news that about 90% of sewage and 70% of industrial wastewater in developing countries are discharged into rivers without treatment, threatening drinking water safety. The World Health Organization points out that 88% of the world’s diseases should be attributed to unsafe water and lack of related sanitation facilities, and diseases caused by unclean drinking water are more common in developing countries.
The issue of drinking water safety is particularly acute in Africa. In April 2007, the African Council of Ministers of Water Resources issued a report that 40% to 60% of people in sub-Saharan Africa do not have clean drinking water, and many African countries are facing water scarcity.
The Asia-Pacific region has also made slow progress in providing safe drinking water and basic sanitation. In October 2007, the United Nations Economic and Social Commission for Asia and the Pacific and other agencies issued a report stating that drinking water conditions for about 560 million people in rural Asia-Pacific have not improved and 1.5 billion people lack basic sanitation facilities.
Even in Europe and the United States, drinking water safety is a serious problem. The UN Economic Commission for Europe recently issued a communique saying that more than 100 million people in Europe still lack safe drinking water. In the area of the 56 members of the Economic Commission for Europe, an average of 37 children die from diarrhea every day due to lack of safe drinking water. In 2006, about 170,000 people in the pan-Europe region became ill due to lack of safe water, of which 120,000 people had hepatitis A.
A recent survey report released by the United States media shows that drinking water in 24 major cities in the United States contains antibiotics and sedatives, and many other pharmaceutical ingredients. At least 41 million people drink this water with potential safety hazards in daily life. The survey, completed by the Associated Press, said that the safety of drinking water in the United States cannot be ignored. From California in the west to New Jersey in the east, drinking water in 24 major cities and regions in the United States is “rich” in pharmaceutical ingredients. In addition to antibiotics and sedatives, there are residual drugs such as sex hormones, anti-inflammatory drugs, analgesics and antipyretics. Investigators have even found 56 pharmaceutical ingredients in Philadelphia’s drinking water.
Water is the source of life, and freshwater resources available for human life are very limited. However, on the one hand, there is a continuous shortage of water resources, and on the other hand, the inexhaustible consumption and pollution of water resources in some areas. The drinking water safety problems caused by this have already adversely affected human health and economic development, and this problem has gradually become a number of countries. Important challenges faced.
