The fungal pathogens Bd and Bsal, causative agents of Chytridiomycosis, are responsible for the extinction of 90 amphibian species and population declines by 90% in another 124 species. In all, 500 amphibian species have been negatively impacted by the Chytrid fungi. These fungi collectively represent the largest pathogenic threat to global biodiversity. Responsible actions to control future spread include boycotting pet shop amphibians and taking necessary precautions against spreading the fungal spores when traveling to sensitive environments. Inaction will condemn delicate species, such as those shown, to extinction.
