This paper describes the symbolic and material aspects of relationships between members of the working class and the environmental issue. A principle of realism prompts members to reintegrate this issue in their material living conditions and to understand it based on a preference for what is concrete, reasonable, and respectable. However, as evidenced by two empirical studies, an ethnographic one and another drawing on interviews, this realist relationship takes different forms depending on class fractions. Our data reveals internal conflicts among the more vulnerable fractions of the working class and diverging upward dynamics among the stabilized ones.
