Most of Earth's water (about 97%) is saltwater found in oceans, which is not suitable for drinking or irrigation without desalination. The remaining freshwater is mostly locked in glaciers, ice caps, and underground aquifers, making it inaccessible for immediate human use. Factors like pollution, contamination, and uneven distribution also contribute to the scarcity of usable water.
