Pollution affects not only humans. Animals of all kinds are subject to the same ills.
Frogs are extremely sensitive to environmental changes and in Asia, species are becoming extinct before they are even identified.
Other contributing factors to the problem of worldwide extinction of many amphibians are disease and habitat encroachment by humans.
All animal species are interdependent. Frogs help keep insect populations in check and they are a food source for other animals who are food sources for still other animals and so on. This means that the effects of a loss of one species can in turn affect the survival of others.
While scientists have been heavily focused on amphibian conservation in Europe and the Americas, more research is necessary in Asia to study the problems relating to frogs and other amphibians.
