This is a very nice analysis of the shortcomings of behaviour change at the level of the individual. Better to focus on systemic failings than guilt-tripping people for making a wrong choice, when it very often isn’t really a choice at all.
When the focus is on practices, the so-called “value-action gap” can no longer be interpreted as evidence of individual ethical shortcomings or individual inertia. Rather, the gap between people’s attitudes and their “behaviour” is due to systemic issues: individuals live in a society that makes many pro-environmental arrangements rather unlikely.
