Hindering Harm and Preserving Purity: How Can Moral Psychology Save the Planet?

The issues of climate change and environmental degradation elicit diverse responses. This paper explores how an understanding of humanmoral psychology might be used tomotivate conservation efforts.Moral concerns for the environment can relate to issues of harm (i.e., causing pain or impinging on another’s welfare) or impurity (i.e., engaging in sacrilegious, polluting, or disgusting actions). Aversions to harm are linked to concern for current or future generations, non-human animals, and anthropomorphized aspects of the environment. Concerns for purity are linked to viewing the environment as imbued with sacred value and therefore worthy of being protected at all costs. While both harm-based and purity-based framings of environmental issues can sometimes backfire, we argue that making these moral concerns salient can nevertheless bring about moral responses to environmental issues. In sum, scientists’ emerging knowledge about the moral mind can be used to facilitate the sustainable conservation of the planet.
