Not that far off-topic, apart from my love of frogs, the "other" reason for my doing this frog series is...
"No group of animals has a higher rate of endangerment than amphibians. Scientists estimate that a third or more of all the roughly 6,300 known species of amphibians are at risk of extinction. The current amphibian extinction rate may range from 25,039 to 45,474 times the background extinction rate.
Frogs, toads, and salamanders are disappearing because of habitat loss, water and air pollution, climate change, ultraviolet light exposure, introduced exotic species, and disease. Because of their sensitivity to environmental changes, vanishing amphibians should be viewed as the canary in the global coal mine, signaling subtle yet radical ecosystem changes that could ultimately claim many other species, including humans." -Center for Biological Diversity
