Limited resources. With the rapid development of industrial production in China, we should not think that environmental resources are inexhaustible. Cherishing resources has also become a major measure to benefit mankind. To this end, the State Council has promulgated some decrees and made a five-year plan for China's resource protection, which indicates that China's environmental resources work has entered a new development stage.
At present, China has nine legal management systems focusing on protecting and saving land resources, which has laid a solid foundation for us to establish the awareness of resource protection. In order to protect environmental resources, China has established various facilities, such as the Ecological Demonstration Zone of the Ministry of Ecology and the "Green School". China is gradually moving towards a road with low resource consumption and less environmental pollution. We need to re-establish the harmony between man and nature.
Because human beings do not cherish resources, natural resources such as minerals, land, fresh water, forests, wild animals and plants are gradually in short supply under the condition of growing population. For pessimists, resources are limited, and part of them will be reduced if they are consumed; Moreover, the total amount of renewable resources is limited, which can not bear the growing demand.
Resources will also become the limiting factor of economic growth, which will eventually stop it.
On the other hand, optimists believe that due to technological progress, the scope of available natural resources will continue to expand; The efficiency of human industry in using resources will be improved, and the situation of insufficient resources will always change. Although their discussion of resources is "contradictory". However, the shortage trend of land, fresh water, forest and other resources in some areas can not be ignored.
It is self-evident that it has caused difficulties to the economic development of these areas. But in a word, resources are indeed an indispensable part of human life.
In order to solve the crisis of resource shortage, human beings try to find new alternative energy sources from solar energy, hydropower, wind energy and bioenergy. However, the technical problem is a big obstacle, and solar energy changes greatly with day and night, sunny and rainy, and seasons, so it is difficult to become a large-scale industrial energy source, which can only meet the needs of families and some special needs.
The growth rate of water energy can't keep up with the growth rate of energy consumption, which has an inestimable impact on ecology and biological chain.
Therefore, people are devoting themselves to the research and development of power generation in controlled nuclear fusion, and people have high hopes for it, comparing it to "artificial sun" and calling it "a monument left by people to future generations in the 2 1 century". But we need to re-establish the harmony between man and nature.
