On December 6, 1998, a piece of paper from the State Council changed the fate of Dongchuan City in Yunnan Province. The prefecture-level city established in 1958 was officially revoked and became the Dongchuan District under the jurisdiction of Kunming. This is the first city in China that has disappeared due to the depletion of mineral resources. The once glorious “millennium copper capital†has disappeared, leaving only a legend that has cast 70% of the Qing Dynasty.
Resource depletion is an inevitable problem caused by the exploitation of mineral resources. Regardless of petroleum and coal, or metal and non-metallic, is not a gift from God, but through millions of years of geological changes or even hundreds of millions of years of formation. The place where mineral resources are developed, the crowds gather, the industry is developed, and it gradually becomes the center of economic activity. However, when the recoverable reserves are declining or depleted, the whole city will rapidly fall into a downturn, industrial benefits will decline, social development will stagnate, and unemployment will rise.
Environmental pollution is another problem caused by the development of mineral resources. Take coal mining, not only directly damage the surface soil and vegetation, but also spontaneous combustion or dust in the storage and loading and unloading, destroying the land and polluting the atmosphere. Those super-oil tankers that transport crude oil will cause serious marine pollution incidents in the event of crude oil leakage. As for the waste water, waste gas and waste residue discharged from the mineral processing process, the surrounding ecological environment is seriously damaged.
In the face of these problems, human beings still have "there are ways to do it." Transformation and sustainable development are the way out of resource-exhausted cities to get out of trouble; the implementation of green mining can not only optimize resource development, but also minimize the impact on the ecological environment. Of course, these require humans to plan ahead and grab a timely turn before the red light appears. Otherwise, it will be too late to wait until it is really exhausted or polluted.
