The Hidden Distribution of Earth's Fresh Water Resources

The video explores the distribution of Earth's water, highlighting that 96.5% is salt water, while only 2.5% is fresh water. Of this fresh water, 70% is in glaciers, 30% is groundwater, and 1.2% is surface water. Further analysis shows that a mere 0.03% of Earth's water is easily accessible as fresh surface water, found in lakes, rivers, and other sources.
