A growing evidence base explores the mental health dimensions of global environmental change. What are the mental/cognitive benefits of exposure to “intact” nature? What are the mental health costs of environmental degradation? Are there significant mental health benefits of managing natural systems in particular ways? Are the mental health burdens associated with reduced exposure to nature fairly distributed across different populations? Better understanding of these issues could meaningfully inform resource management decisions and urban design to mitigate the mental health impacts of environmental change.
