Unicef

On World Water Day, as on every other day, some 2.5 billion people are "doing their business" somewhere other than in a toilet or latrine. Thatis not a statistic many people want to examine too closely, but it is crucial data for efforts to meet the Millennium Development Goals on improving global sanitation and reducing child mortality.

At the United Nations Climate Change Conference now under way in Bali, Indonesia, UNICEF has held a series of events to highlight the effects of global warming on children and to ensure that young people are involved in debate on this issue.
