The economic growth of countries worldwide is linked to the environment, in the sense that the greater economic growth, the greater pollution. This is because all the inputs or materials that are used for the production of products are located on planet earth, and the use or abuse of the natural resource harms the environment to a great extent. On this economic-environmental issue, it is necessary to mention the Kusnetz Environmental Curve (CAK), which relates the environment to the level of per capita income of the economy of developed, underdeveloped and developing countries. Specifically, the CAK measures environmental deterioration with respect to per capita income; and when it reaches the threshold, it is translated as the zone of maximum environmental deterioration. Now, what happens when it starts to fall? There may be a long-term effect that benefits economies.
