Approximately 1/6 of the human population does not have access to clean drinking water. So much death and illness is caused by a lack of sanitation and the inaccessibility of water. Every 20 seconds a child dies as a result of water related diseases. Half of the hospital beds in the world are occupied by patients suffering from diseases associated with lack of access to safe drinking water, inadequate sanitation and poor hygiene. Take that in for a minute.
