Amphibians are the world's most threatened vertebrate group, with multiple simultaneous pressures causing population collapses globally.
Amphibians dying from chytridiomycosis experience cardiac failure as their skin loses ion transport function. The scale of this - potentially billions of individuals across hundreds of species - represents extraordinary suffering. Habitat loss through wetland drainage eliminates the breeding sites entire populations depend on, causing death through desiccation and failed reproduction. Climate change disrupting rainfall patterns creates temporal mismatches between breeding timing and water availability. The precautionary principle applied to amphibian welfare would suggest conserving water quality and wetland habitats as urgent priorities given the numbers of animals affected and the severity of their decline.
