This paper observes how the social, political and legal life of rights continues to evolve in response to growing natural resource scarcity and deteriorating climate conditions worldwide. In particular, it assesses the type of interpretive repertoires actors bring to bear on issues of justice between generations and human rights eligibility, documenting arguments put forward in defense, as well as against assigning a rights status to those not yet born. It notes how scientific research documenting the ‘forcing effects’ of escalating atmospheric pollution on long-term planetary wellbeing triggers a new conversation on the limits of traditional approaches to environmental justice and highlights the need to consider once again how a more long-term perspectivism on duties, rights and responsibilities can be institutionally applied.
