8PBr spent some time looking at water and sanitation last week, and were shocked to discover that 1.1 billion people - about a sixth of the world's population - do not have access to clean, safe water... And that 2.6 billion people - about 40% of the world's population - do not have access to adequate sanitation.
The picture below (from Ecumenical Water Network) was taken in Kibera - a slum in Nairobi, Kenya. For those people who cannot afford to pay to use a filthy latrine, the alternative is a plastic bag, which ends up in the street. These so-called "flying toilets" contribute to the horrifying statistic that 1.8 million children die before the age of 5 - from diarrhoea.

BBC correspondent, Fergal Keane, visited Kibera yesterday, to coincide with the launch of the United Nations International Year of Sanitation. You can watch his report here.
