River dolphins including the Ganges, Irrawaddy, and Amazon pink dolphin face habitat degradation, entanglement, and pollution in freshwater systems with limited conservation infrastructure.
River dolphins surviving in heavily polluted, trafficked waterways face a gauntlet of welfare harms including noise-impaired echolocation, chemical contamination, direct persecution, and entanglement. The extinction of the baiji represents the permanent loss of a unique evolutionary lineage and a massive welfare failure. Remaining river dolphin species require emergency protection to avoid similar fates.
