When it comes to conservation, what you don’t know really can hurt you. That’s why a group of more than a dozen horizon scanners, researchers and others gather each year to identify relatively obscure threats and opportunities that could, if they bubble to the surface, have a big impact on our ability to protect biological diversity. This year’s prognostication, published in Trends in Ecology & Evolution earlier this month, identifies 15 hot topics lurking in the wings. Among them: Response of financial markets to unburnable carbon, land loss in Southeast Asia from subsidence of peatlands, the discharge of polyisobutylene into ocean water and the resurrection of extinct species.
