For most Americans, a clean glass of water is just a faucet(水龙头) away. But for many of the world’s poorest people, it’s hard to get.
On Wednesday, the United Nations(UN)marked World Water Day by trying to cut the number of people without good drinking water—one billion human beings worldwide –in half．In the next ten years, the UN will work with governments around the world to reduce the shortage.
Without clean water nearby, many people use water that is not clean. In India, many people bathe and wash their clothes in rivers that are polluted by human waste.
According to the UN, not having enough clean water and sanitation(卫生设施) causes more than three million deaths a year.
The links between water and human health are powerful,said Dr Lee Jong Wook, director-general of the World Health Organization (WHO)．—We cannot live without clean water.
In fact, the International Federation of the Red Cross said that quick reaction after last year’s Asian tsunami had stopped disease．The agency provided clean water to nearly 500,000 people in Indonesia and Sri Lanka after the tsunami.
World Water Day was first celebrated in 1993. Since then, it is celebrated each year on March 22
