" So many wells have been dug in Changzhou that its groundwater has been over-exploited, and the local ground level has sunk by two feet. The city has officially banned new wells and mandated the installation of pollution controls, but China’s endemic corruption ensures that neither measure has much meaning. "
- Charles C. Mann

The quote highlights a significant environmental issue faced by Changzhou, a city in China, where excessive drilling of wells has led to severe depletion of groundwater resources. As a consequence, the ground level has lowered by two feet due to the removal of water from beneath the surface. This over-exploitation prompted local authorities to ban the creation of new wells and enforce regulations for pollution control; however, corruption within the government undermines these efforts.

The deeper meaning behind this statement underscores the broader issues of environmental management and governance in China. The excessive exploitation of natural resources often stems from a combination of economic pressures and inadequate regulatory enforcement. Corruption exacerbates these problems by enabling individuals or groups to circumvent laws designed to protect the environment, leading to further degradation of natural resources and public harm. This situation not only affects local ecosystems but also poses long-term challenges for sustainable development.
