8. Increasing Water Shortages The amount of freshwater stays the same, while Earth’s population continues to grow. China—polluted rivers, shrinking aquifers in the midst of a growing population Egypt—dependent on Nile River; countries to Egypt’s south may affect the river’s flow

9. Climate Change and Water Supplies Some scientists believe global warming will lead to reduced rainfall in some areas and flooding in others Managing water supplies: Water collection and storage—if your country has too little water Flood control—if your country has too much!

10. Factors affecting freshwater availability Population growth Future climate changes Pollution of formerly safe drinking sources

11. Future concerns Increased cost of water $$$$$$$$$$$$$$$ Lower food production Public health problems
