Environment activists have urged restrictions on frog consumption — especially frogs harvested from the wild — because frogs are an essential element of the ecosystem. Conservationists have warned that frogs could be going the same way as the cod — gastronomic demand is depleting regional populations to the point of no return. Like most amphibians, frogs with their thin and moist skin are sensitive to environmental changes and pollution. The population of amphibians is threatened and declining globally due to habitat degradation, environmental destruction, and pollution.
