S01E03 Fresh Water

Freshwater, making up just 3% of the Earth's water supply, is crucial for the planet's weather patterns and erosion processes. It serves as a vital resource for all non-marine wildlife, providing drinking water and habitats for swimming, breeding, and hunting. Ecosystems like rivers, lakes, and swamps are rich in life, hosting a diverse array of aquatic and other species that have evolved to thrive in these wet environments.
