2.1 bn lack safe drinking water, 4.5 bn lack sanitation: WHO
Around 2.1 billion people lack access to safe drinking water at home, whereas 4.5 billion lack adequate sanitation, according to the World Health Organization (WHO). The 4.5 billion number includes 600 million who share a toilet with other households, while 892 million defecate in open. Safe water and sanitation at home shouldn't be a privilege, but a right, WHO said.
