Freshwater Resources
Less than 0.01 percent of Earth's water is fresh and unpolluted, vital for life
20 Jan 2026
0
What is the primary reason that only a tiny fraction of Earth's water is available as fresh and unpolluted freshwater resources?
Freshwater resources are abundant but mostly polluted, making them unusable.
Most of Earth's water is saline or locked in glaciers and ice caps, limiting accessible fresh water.
Freshwater is evenly distributed globally but is overused in all regions.
