A Green Tree Frog crawls out of a pitcher plant, where the pooled water keeps the amphibian moist and hydrated.
Over the past 50 years, scientists have recorded major declines in frog populations around the world. A few species have vanished completely.
Many frogs die as the result of local human activity, but the epidemic has also reached remote areas. Is there a global cause? Scientists continue to search for answers.
Among the causes factoring into population declines are:
- Habitat destruction by human development
- Introduced species that prey on frogs or affect the food chain
- Chemical pollution
- Climate Changes
- Over-collection as a food source
- Epidemic diseases
