The inverted-U relationship (also known as the environmental Kuznets curve) suggests that as per capita income increases beyond a certain point, environmental degradation first increases and then decreases. This relationship has been observed for sulfur dioxide pollution in air, as seen in countries such as the United States, United Kingdom, and Japan. However, it is not typically observed for the other options listed. For example, carbon dioxide emissions tend to increase with increasing per capita income, while lead pollution in water and airborne heavy particles tend to decrease as income increases.
