While our common frog appears to be safe, amphibians are the most threatened group of animals on earth: nearly one-third of the world’s 6,435 amphibian species are threatened with extinction and at least 150 species have completely disappeared since 1979. Save the Frogs Day on April 28th is trying to draw attention to this problem (http://www.savethefrogs.com). For more on threats to frogs globally and what we can do to protect them please also visit http://citypollen.blogspot.com/2009/03/save-frogs.html. Thanks!
