“…As with climate change interventions, there is a clear need for a more systematic understanding of the technical potential of different behaviour changes: which ones, if delivered, would be most likely to reduce a threat and thereby enhance the status of the conservation target, taking into account other threats it faces 80,91 ? Given the focus of many recent environmental interventions on appealing, tractable but relatively low-impact behaviour changes (for example, eating more locally grown food or avoiding plastic drinking straws), such prioritization is badly needed 88,90 . One challenge in identifying priorities may be the complexity of conservation outcomes: estimating probable impacts of behaviour changes on highly interconnected ecosystems may be more difficult than impacts on greenhouse gas levels 80 , but we suggest that this is a surmountable problem.…”
