Explanation

The income-environment relationship is defined by the Environmental Kuznets Curve (EKC), which posits an inverse-U shaped relationship between economic development and pollution [1]. In the beginning stage, environmental degradation increases as the economy shifts from agrarian to industrial, driven by rapid urbanization, industrialization, and a priority on material output over environmental quality. As income rises, the trend eventually reaches a 'turning point'. In the later stage, pollution declines due to structural changes where the economy shifts toward the services sector and technologically-driven, cleaner industries. This transition is further supported by increased demand for environmental quality, better regulatory mechanisms, and the adoption of resource-saving technologies [1]. Thus, all three statements accurately describe the theoretical stages and structural drivers of the EKC hypothesis.
