The island of Madagascar, off the coast of Africa, is an environmental hot spot in two ways one good, one bad. On the plus side, the island is considered one of the most biologically diverse places on Earth. A May study in Proceedings of the National Academy of Sciences showed that, if anything, that's an understatement. Scientists identified an astonishing 129 to 221 brand-new species of frogs, which almost doubles the number of amphibian species on the island in a single stroke. And if amphibians were so seriously undercounted, said researchers, a thorough survey might well find the same to be true of other animal groups. Unfortunately, there's also a minus side: Madagascar has already lost some 80% of its rain forest crucial habitat for its many species to logging, and despite some effort to preserve the rest, there's a real danger that one of the most biodiverse places on the planet could be losing more species than anywhere else.
