説明
<jats:p>The world's amphibians face an imminent extinction crisis, with nearly a third of species categorized as threatened. The principal cause of amphibian declines is the destruction of freshwater habitats.

Amphibian declines and extinctions are evidence of the harmful effects of humans on natural ecosystems.</jats:p>
