4.5 billion people throughout the world still don't have access to a toilet.
Meanwhile, around 892 million people still practice open defecation.
The United Nations says exposure to human faeces on such a large scale has a devastating impact on public health, nutrition and education worldwide.
Today marks World Toilet Day - a campaign day which aims to raise awareness that not all people have safe access to a toilet, and the daily risks they face.
The latest figures show around 900 million schoolchildren worldwide have no hand-washing facilities which is also proving to be a major factor in the spreading of deadly diseases.
The UN aims to ensure open defecation is eradicated by 2030, but fears the world is not on track to meet this target.
