Availability of Freshwater

The video explains the distribution of Earth's water, highlighting that 97% is saline and only 3% is fresh. Of this, a small fraction is readily available for use, as most is trapped in ice caps or underground. The water cycle plays a crucial role in renewing fresh water, involving processes like evaporation and precipitation. Despite its importance, fresh water is limited, and increasing human activities are leading to scarcity. The video emphasizes the need for awareness and conservation to address the growing water crisis.
