Wat-er wonderful world!. Happy World Water Day!

March 22 is World Water Day, a United Nations initiative highlighting the importance of freshwater and its conservation. This day raises awareness about the global water crisis and promotes actions to ensure clean water for all. Freshwater is vital—not just for drinking, but for ecosystems, agriculture and cultural heritage.

One stunning example of nature's freshwater wonders is Cenote Nicte Ha in Tulum, Mexico—featured in today's image. A cenote is a natural sinkhole that arises from the collapse of limestone bedrock, exposing groundwater. Named after the Mayan words for flower 'Nicte' and water 'Ha,' this open cenote is known for its crystal-clear turquoise waters and beautiful water lilies. Sunlight filters through its open surface, supporting vibrant aquatic life. For the ancient Maya, cenotes were sacred portals to the underworld and vital water sources in the Yucatán Peninsula. With a maximum depth of approximately 10 metres, Cenote Nicte Ha remains a popular spot for snorkelling and diving, offering a glimpse into an ancient and fragile ecosystem. Freshwater is not only essential to life—it's life! Let's protect it for future generations!
