This essay argues that we have a duty to protect biodiversity hotspots, rooted in an argument about the wrongful imposition of risk and intergenerational justice. State authority over territory and resources is not unlimited; the state has a duty to protect these areas. The essay argues that although biodiversity loss is a global problem, it can be tackled at the domestic level through clear rules. The argument thus challenges the usual view of state sovereignty, which holds that authority over territory, resources, and migration (all of which are connected to the protection of biodiversity hotspots) is unlimited.
