CLEAN WATER IS A BASIC HUMAN RIGHT !
According to the World Health Organization ( WHO ), in 2002 some 1.1 billion people lacked access to improved water sources, 2.6 to basic sanitation, and approximately 1.8 million people die every year from diarrhoeal disease, 90 percent of them children under the age of five. The World Water Crisis is serious and widespread, but there is hope. All over the world, people are working to resolve this crisis, and prevent the death and suffering of millions of children and their families. Get involved in World Water Day 2005 - March 22nd - and become part of the solution!
