Question

Quizplus · Accepted Answer

The low population density along with a low level of economic development in Central Asia has contributed to the relatively clean environment. The lack of heavy industrialization and limited urbanization in the region has helped to preserve the natural environment. Though other factors like stringent environmental standards and controls or favorable breezes may play a role, they are not as significant as the low population density and level of economic development.
