Frogs aren't well known for their sense of humour, but they might need to develop one in coming decades. Perhaps more than any other order of animals, frogs and toads are under threat--from phenomena like climate change and habitat destruction and a mysterious fungus called Batrachochytrium dendrobatidis. Several rainforest species have gone missing in recent years and others are becoming rarer: according to the recent Global Amphibian Assessment, 1653 of the 5067 known frog and toad species globally are either threatened or extinct.
This edition of the TFU is not about frogs. But these moist and vocal creatures are as good a symbol as any of the challenges facing advocates of natural tropical forests.
