Ecology has a key role in our understanding of the benefits that humans obtain from ecosystems (i.e. ecosystem services). Ecology can also contribute to developing environmentally sound technologies, markets for ecosystem services and approaches to decision-making that account for the changing relationship between humans and ecosystems. These contributions involve basic ecological research on, for example, the resilience of ecosystem services or relationships of ecosystem change to natural disasters. Much of the necessary work involves interdisciplinary collaboration among ecologists, social scientists and decision makers. As we discuss here, ecology should help formulate positive, plausible visions for relationships of society and ecosystems that can potentially sustain ecosystem services for long periods of time.
