These substances do not always change the colour of the water, meaning that they are often invisible pollutants.
Are humans responsible for the shortage of water?
Human activity is a major cause of water scarcity due to the use of fossil fuels that alter climate and weather activity, as well as the rapid increase in global population consuming more water. In order to provide for a growing population, dams and irrigation systems are built to supply fresh water to remote areas.
Who affects water scarcity?
Women and children are worst affected – children because they are more vulnerable to diseases of dirty water and women and girls because they often bear the burden of carrying water for their families for an estimated 200 million hours each day.

Can you drink sea water if boiled?
Making seawater potable
Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).
