AB  - How do people value environmental resources? To estimate public valuation of 
      natural resources, researchers often conduct surveys that ask people how much 
      they would be willing to pay to preserve or restore threatened natural resources. 
      However, these survey responses often elicit complex affective responses, 
      including negative reactions toward proposed destructive land uses of those 
      resources. To better characterize processes that underlie the valuation of 
      environmental resources, we conducted behavioral and neuroimaging experiments in 
      which subjects chose whether or not to donate money to protect natural park lands 
      (iconic versus non-iconic) from proposed land uses (destructive versus 
      non-destructive). In both studies, land use destructiveness motivated subjects' 
      donations more powerfully than did the iconic qualities of the parks themselves. 
      Consistent with an anticipatory affect account, nucleus accumbens (NAcc) activity 
      increased in response to more iconic parks, while anterior insula activity 
      increased in response to more destructive uses, and the interaction of these 
      considerations altered activity in the medial prefrontal cortex (MPFC). Further, 
      anterior insula activity predicted increased donations to preserve parks 
      threatened by destructive uses, but MPFC activity predicted reduced donations. 
      Finally, individuals with stronger pro-environmental attitudes showed greater 
      anterior insula activity in response to proposed destructive uses. These results 
      imply that negative responses to destructive land uses may play a prominent role 
      in environmental valuation, potentially overshadowing positive responses to the 
      environmental resources themselves. The findings also suggest that neuroimaging 
      methods might eventually complement traditional survey methods by allowing 
      researchers to disentangle distinct affective responses that influence 
      environmental valuation.
