Pristine lakes are bodies of freshwater that remain largely untouched by human activity. They are characterized by their clear waters, vibrant ecosystems, and minimal pollution. These lakes often serve as habitats for various species of fish, birds, and plants, contributing to biodiversity. Many pristine lakes are found in remote areas, such as national parks or protected regions, where conservation efforts help maintain their natural beauty. Examples include Lake Baikal in Siberia and Lake Tahoe in California. These lakes are not only important for wildlife but also provide recreational opportunities for activities like fishing, kayaking, and hiking.
