Amphibians (which include frogs and salamanders among other species) are the most endangered group of animals on the planet. Everything seems to be working against their survival: their habitats have been reduced and deteriorated by the advance of agriculture, the logging industry and human infrastructure. In the past two decades, a series of pathogens have decimated them. And so far this century, climate change threatens to put an end to them. A report in which more than a hundred scientists have participated, with additional data from another 900 from around the world, concludes that we must hurry if we want to save them. The International Union for Conservation of Nature (IUCN) maintains a Red List with the conservation status of all known life. The prestigious journal Nature has just published the second Global Amphibian Assessment (EGA) for this list.
