Global Fresh Water Usage and Management

The video discusses the critical role of water in sustaining life and civilization, highlighting that 97.5% of Earth's water is salty ocean water, leaving only 2.5% as fresh water. This fresh water is divided into surface water, ice caps, and ground water. Surface water is minimal, ice caps hold a significant portion but are not easily accessible, and ground water is abundant and crucial for human use. The video also explores how industrialization and population growth have increased fresh water demand, with agriculture consuming 70%, industry 22%, and domestic use 8% of global fresh water.
