Frank Adloff (* 1969) is well-known for his work on sustainability and prosocial behavior (gift-giving). 

In "Politics of the Gift" Adloff argues that gift-giving is a fundamental aspect of human social interaction and that it plays a key role in shaping social relationships and the distribution of resources. Gift-giving is a form of symbolic communication that is used to establish and maintain social bonds; it is a central aspect of social life in many cultures.

In "Gifts of Cooperation, Mauss and Pragmatism" Adloff explores the connections between the work of French sociologist Marcel Mauss and the tradition of American pragmatism, arguing that both offer valuable perspectives on the role of gift-giving in shaping social relationships and the distribution of resources. Mauss tends to focus on the symbolic and cultural significance of gift-giving, while American pragmatism tends to view it more in terms of the practical and instrumental benefits it can provide.

Below, you can see Adloff's lecture "Nature and society in the Anthropocene: gifts, conviviality, symbioses. For more, read one of his books. I especially recommend reading 'Politik der Gabe: Für ein anderes Zusammenleben' / "Politics of the Gift".
