Our Earth has plenty of water (about 1.386 × 10¹⁸ cubic meters). But only 2.5% is potable, out of which the surface freshwater easily accessible to all life forms is even skimpier (~0.008%), carried by rivers and lakes.
Freshwater lakes are among the most convenient sources of drinking water available worldwide.
This list contains the seven world’s largest freshwater lakes, ranked by their surface area.
Here are the world's 7 largest freshwater lakes by surface area:
