frogs and toads are disappearing

Explanation:

      Scary new evidence suggests that amphibians may be in worse shape than previously thought due to climate change. In addition, findings indicate that the decline 70 per cent in amphibians over the past 35 years may have been surpassed by a sharp drop in the reptile population, even in Costa Rica's once-intact habitats. Worryingly, the new research warns that the strategy protected areas for biodiversity will not be sufficient to prevent extinction. Frogs and their relatives are in big trouble.

   Scientists say amphibians - cold-blooded animals that include frogs, frogs, salamanders and angels - are under serious threat due to climate change, pollution and the onset of a fatal and infectious fungal disease that has been linked to global warming.

    Scientists say the worldwide decline of amphibians is one of the world's most pressing environmental problems; one that can foreshadow major threats to the planet's ecological balance. Because amphibians have highly permeable skin and spend portions of their lives on water and land, they are sensitive to environmental change and can act as the proverbial “coal mine canary,” indicating the relative health of an ecosystem. As they die, scientists are left wondering which group of animals or plants is next.
