1 Natural resources Natural resources generally refer to all material resources and natural processes, and usually refer to resources that are beneficial to human beings under certain technological and economic environmental conditions. Natural resources can be classified from different perspectives. From the perspective of the renewability of resources, it can be divided into renewable resources and non-renewable resources
Renewable resources: resources that can be regenerated with human participation, such as farmland, which, if cultivated properly, can make the soil constantly new and continuously provide new agricultural products for human beings. There are two types of renewable resources:
One is resources that can be recycled, such as solar energy, air, rainwater, wind and hydropower, tidal energy, etc.; One category is biological resources. Non-renewable resources: (or depleting resources), the reserves, volume of such resources can be measured, and their quality can also be reflected by the percentage of chemical composition, such as mineral resources.
The distinction between renewable resources and non-renewable resources is relative, such as oil and coal are non-renewable resources, but they are the result of long-term physical and chemical changes in the stratum of paleontology (ancient animals and plants), which shows that the two can be transformed, which is the manifestation of the law of immortality of matter and conservation and transformation of energy. From the degree of controllability of resource utilization, it can be divided into exclusive resources and shared resources. Proprietary Resources:
Such as resources controlled and under the jurisdiction of the state. Shared resources: such as the high seas, space, information resources, etc.

Of course, it's the Rolls-Royce Silver Charm, worth 100 million pounds (1.3 billion yuan, because the exchange rate changes frequently); According to its owner: "If you look at it as a work of art, it is worth 100 million pounds or more, because many of the paintings of the world's famous masters are about 100 million dollars, and the paintings can only be seen, and my Rolls-Royce can not only see but also move; But it's by no means the best car in the world, and if you look at it as an average car, it's probably worth only £395, maybe a little less."
Remember to adopt it.

The United States has 14 strategic nuclear submarines, 57 attack nuclear submarines. Russia has 12 strategic nuclear submarines (only 8 are operational, of which 1 Russia has only 10 missiles at its disposal, 2 air boats that do not have missiles available for them, and 2 are under construction. , more than 30 attack nuclear submarines. China has 3 strategic nuclear submarines (which do not yet have the capability of ocean-going combat readiness duty), 6 attack nuclear submarines. Britain has 4 strategic nuclear submarines, 8 attack nuclear submarines.
France has 4 strategic nuclear submarines, 6 attack nuclear submarines. In addition, India completed and commissioned one strategic nuclear submarine last year. This is the number of nuclear submarines currently in service in the world, and the number of other conventional submarines is somewhat higher, and the total number cannot be counted.
China has the largest number, with about 55 ships. Other countries such as Russia, Germany, Japan, France, Sweden, South Korea, and Israel have a considerable number of conventional submarines, as well as a small number of Russian, German, and American-built submarines purchased by some small countries.
