The functional extinction of the Baiji river dolphin was declared in 2006 after extensive surveys failed to locate any individuals in the Yangtze River. Habitat degradation from dam construction, pollution, and overfishing contributed to the decline of this species. The Baiji's extinction highlights the urgent need for conservation efforts and raises awareness about the fragility of aquatic ecosystems.

The functional extinction of the Baiji river dolphin in 2006 prompted eco-poetry highlighting ecological collapse. Poets like Aimee Nezhukumatathil and Jorie Graham addressed human impact on freshwater ecosystems, advocating for environmental awareness and the urgent need for conservation.
