Imagine a world without the natural wonders that contain about 90% of Earth's surface freshwater. Lakes provide drinking water, support wildlife, help regulate climate and sustain communities around the globe. In recognition of their vital role, the United Nations designated 27 August as World Lake Day, first observed in 2025. The observance has particular relevance for Canadians, as Canada is home to more than two million lakes that shape its landscapes, ecosystems, recreation and freshwater resources. Protecting them is increasingly important as pollution, overuse and climate change put pressure on many lake environments.

Pictured here is Lake Magadi, a shallow alkaline lake in Kenya's Great Rift Valley. Its mineral-rich waters support abundant algae, attracting vast flocks of lesser flamingos that gather there to feed. The birds' pink hues often transform the shoreline into a dazzling spectacle. On World Lake Day, scenes like this remind us that healthy lakes support remarkable wildlife and help sustain life far beyond their shores.
