As the human population increases, the demand for water resources also increases. This is because more people require water for drinking, cleaning, sanitation, and agriculture. As a result, water scarcity becomes an issue in many areas, leading to water stress, droughts, and depletion of groundwater resources. Examples of this can be seen in regions like California, India, and South Africa, where water scarcity is becoming increasingly problematic due to the growing population and changing climate.
Increases in the human population have significant impacts on water resources. Firstly, the demand for freshwater increases as more people require water for drinking, sanitation, agriculture, and industrial purposes. This leads to overextraction of groundwater and surface water, causing depletion of water sources. Additionally, population growth puts pressure on ecosystems, leading to habitat destruction, pollution, and reduced water quality. For example, in highly populated areas like cities, water supply systems often struggle to meet the increased demand, resulting in water shortages, rationing, or the need to extract water from distant sources.
