Freshwater is a limited natural resource and crucial for the sustenance of life on earth.
The earth has 1.386 billion km³ of water, with only 2.5% being freshwater, and just 0.3% available as liquid water.
Freshwater habitats house 10% of animals and 40% of fish species, and are crucial for drinking, agriculture, electricity generation, and climate regulation.
Human activities are affecting the quality of freshwater sources through pollution, garbage, and excessive development, leading to depletion of freshwater.
Several international organizations are working to clean freshwater sources and prevent contamination to ensure safe drinking water for all.
No freshwater seas or oceans exist worldwide, but some significant freshwater bodies include Lake Superior, Lake Victoria, Lake Huron, Lake Baikal, and the Sea of Galilee.
These freshwater bodies are significant for economic, cultural, and religious reasons, and are home to unique flora and fauna.
Freshwater bodies also promote tourism and provide essential resources for local communities.
