The endangerment of the giant ditch frog due to demand for frog legs is a good example of what is happening to many of the world's endangered frog species. In the last 10 years, the giant ditch frog population has plummeted by 80 percent, primarily through consumption. Aside from overhunting, frogs worldwide also must contend with habitat loss, pollution and the fungal disease chytridiomycosis, which now threatens almost all frog populations.
