Amphibians are experiencing the most severe vertebrate extinction crisis in history, with chytrid fungus causing mass die-offs and immense individual suffering.
Wild amphibian welfare is a crisis of extraordinary scale. Chytridiomycosis causes a slow, distressing death through cardiac failure driven by electrolyte loss — a welfare harm experienced by millions of individual animals in dying populations across the world. The scale of the crisis — hundreds of species affected, some populations completely eliminated — means the aggregate suffering is enormous and the conservation implications are devastating for ecosystems that depend on amphibians as prey, predators, and decomposers. Individual welfare and conservation interests are perfectly aligned here: protecting amphibians from Bd, reducing the pet trade spread, and restoring populations serves both the welfare of individual animals and the ecological integrity of their habitats.
