My zoology students each recorded a podcast on the plight of a different endangered species of amphibian. They are sharing their work with the world on this website: http://endangeredamphibians.blogspot.com/
This is an especially relevant conservation issue because currently 1900 amphibian species are endangered. Sadly 1/3 of all the amphibian species on earth are at risk of becoming extinct in our life time. On the website, each photo has a link to a podcast.
