Water Scarcity
The way that mankind uses water has not changed much since the days of the Romans. We expect that it will rain, and this rain will fill up lakes, dams and reservoirs and that rivers will keep on flowing. We also expect that boreholes will continue to provide water. We then pump this water to water-treatment-works and from there to our cities and towns.
However, with population growth, pollution and climate change, these assumptions are no longer valid, and we are witnessing droughts, rivers and dams drying up and water levels dropping.
Even though we live on the Blue Planet, the amount of fresh water
that is available for human consumption is limited
