When Robin Moore first saw the Bornean rainbow toad, he felt like he was meeting a celebrity. Moore’s team had spent more than 10 months searching the rainforest in Borneo, an island in Asia, before finally finding it. The amphibian hadn’t been spotted in 87 years.

Moore is a conservation biologist at Global Wildlife Conservation (GWC). The organization’s lost species program lists almost 1,200 species that haven’t been seen for decades—or even centuries. GWC provides funding to search for these species. The goal is to discover whether “lost” species are extinct or just very hard to spot.

Moore believes his success with finding the rainbow toad gives people hope. “It’s very easy to feel very overwhelmed by environmental issues and climate change,” he says. “Don’t feel powerless. You can make a difference. Everybody can.”
