La Menace écologique comme forme de communication. Le point de vue de la théorie des systèmes sociaux de Niklas Luhmann

Résumé

In recent years, ecology has once again risen to the top of the political agenda, attracting the attention of the mass media system. This paper outlines how the social systems theory developed by Niklas Luhmann deals with ecological issues and what is the originality of this approach. It focuses on the ecological threat as a form of communication, on the operational closure of social systems in its relationship with causality, and on resonance. It finally shows that the pandemic COVID-19 could be investigated from this sociological viewpoint as a threat coming from the human environment.
