Liquid fresh water on Earth is considered a limited resource due to several key factors:
1. **Distribution**: Freshwater is unevenly distributed across the planet, with certain regions having abundant supplies while others face scarcity. Only about 2.5% of the Earth's water is freshwater, and much of it is locked away in glaciers and ice caps.
2. **Usage**: The demand for freshwater is increasing due to population growth, agricultural expansion, and industrial activities. This rising demand often outpaces the natural replenishment of freshwater sources.
3. **Pollution**: Many freshwater sources are being contaminated by agricultural runoff, industrial waste, and urban development, which reduces the amount of usable water available.
4. **Climate Change**: Changes in climate patterns are affecting precipitation rates and water availability, leading to droughts in some regions and flooding in others, further complicating the management of freshwater resources.
5. **Depletion**: Over-extraction of groundwater and surface water for agricultural, industrial, and personal use can lead to depletion of these vital resources, making them less available for future use.
These factors collectively demonstrate that while the Earth is covered in water, the supply of accessible and usable fresh liquid water is limited and increasingly under threat.
