This paper focuses on the approach of religions - especially the religions of the book - to the issue of respect for Creation and its preservation, to argue how certain religious practices may themselves constitute a threat to the environment and be a cause of pollution and consumption of resources. Among these practices, the major religious pilgrimages (jubilee pilgrimages, haji, tirtha yatra, etc.) certainly entail risks of environmental sustainability that need to be monitored and countered. Focusing only on the Catholic religion in the Italian scenario, this paper emphasises how minor pilgrimages, especially those linked to religious routes or paths of faith can be a practice to be encouraged.
