SAVE THE FROGS! is an amphibian conservation organization with the goal of saving the frogs. They started Save the Frogs Day on April 30th. They run out of California but have projects around the world like Ghana.
You can help them by becoming a member or making a donation. They also have a gift shop where you can buy items with the proceeds going to the group.
