A major problem is the availability of clean drinking water. Currently clean water is in short supply for approximately 1.1 billion people. According to the United Nations (UN), 6000 people die every day, around two million people each year, because the hygiene is not appropriate and there is no access to clean, safe drinking water. Part of the problem is ‘home made’, the logical consequence of human existence: waste water. 2.4 billion people do not know what to do with their waste water. It is introduced into the environment without any treatment and purification and finds its way maybe into a lower-level drinking water reservoir in the area. According to calculations, one liter of waste water can pollute eight liters of fresh water. Not surprisingly the main sufferers in this issue are people in the developing nations.
