Amphibian decline refers to the significant decrease in populations of amphibians, such as frogs, toads, and salamanders, worldwide. This decline is attributed to various factors, including habitat loss, pollution, climate change, and diseases like the chytrid fungus, which has devastated many species. The loss of amphibians is concerning because they play crucial roles in ecosystems, such as controlling insect populations and serving as indicators of environmental health. Conservation efforts are essential to protect these species and their habitats, ensuring the balance of ecosystems is maintained for future generations.
