Coping with water scarcity
Global water use has been growing at more than twice the rate of population growth in the last century. Water scarcity already affects every continent and more than 40 percent of the people on our planet. By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be living under water stressed conditions.
In order to really understand how serious the problem is we must take stock of the immense impact water has on our daily lives. Lack of access to adequate, safe water limits our ability to produce enough food to eat or earn enough income. It limits our ability to operate industries and provide energy. Without access to water for drinking and proper hygiene it is more difficult to reduce the spread and impact of life-threatening diseases like HIV/AIDS. Every day, 3,800 children die from diseases associated with a lack of safe drinking water and proper sanitation.
