Water is the most abundant substance on our planet, covering 71% of the earth’s surface in the form of oceans, rivers, lake and ice caps. However, less than 1% of the earth’s total water is liquid fresh water. An expanding global population means it is vital we conserve as much as we can for future use for all.
Human beings use water for many activities including for consumption, agriculture and industry. Estimates show that one person requires a minimum of 50 litres of water a day to meet personal and household needs. However, inhabitants of developed countries can use up to 500 litres of water per day.
The UN World Water Development Report predicts that the quantity of water available to human beings will decrease by 30% over the next 20 years. Water scarcity means we must be far better at reducing our consumption.
