Whatever the reason, it should not be wasted. Our resources will be used by the next generation. China's total resources are not low in the world, but we have a large population, and the per capita resources are scarce in the world. China is also in a period of rapid development. Due to the reasons of technology, management and equipment, the efficiency of resource utilization is low, and the waste in the process of development and utilization is amazing. When one resource is used, the effective use of another resource is destroyed. For example, in the production process, the use of mineral resources causes environmental pollution and destroys fresh water resources. In view of the above reasons, we should not waste it, but we are not qualified to waste it at all.
