About 2.5% of the Earth's total water is freshwater. However most of that freshwater is not easily accessible:
- ~68.7% of the freshwater is locked in glaciers and ice caps (including Greenland and Antarctica).
- ~30.1% is groundwater (much of it deep and hard to access).
- ~0.3% is surface water (lakes, rivers) plus soil moisture, permafrost, and atmosphere.
That means only a tiny fraction of the planet’s water — well under 1% of the total — is liquid freshwater in lakes and rivers that people can readily use. (Sources: USGS/global water budgets; exact percentages vary slightly by source.)
