Some of the we alth of the earth's interior, which man uses every day, exists in limited quantities. If the use of alternative substances is not proposed, sooner or later they will run out and the production associated with them will be impossible. In order to understand the prospects for industry and the ecology of the planet, it is worth understanding what natural resources are and which of them can be used without restrictions.
Main classification
Natural resources are the natural we alth used by human society for the economy. As a rule, they are classified based on their origin. According to this division, soil are distinguished first of all. Then it is worth mentioning forest and water. No less important are biological resources. Minerals are classified as mineral raw materials. There are also energy and climate. Exhaustible and inexhaustible natural resources are not included in such a classification. At the same time, they are directly related to almost every type.
Classification by exhaustibility
So, the main types have been studied. It is worth understanding what areexhaustible and inexhaustible natural resources specifically. To determine each variant of we alth to a particular type, it is necessary to pay attention to its renewability. This is a complex concept, since many species have exhaustion limits beyond which it stops recovering. However, the main renewable resources include forests, water, soil, as well as wind, current, solar and climate energy. It is also worth separating the classification by substitutability. The types of inexhaustible natural resources differ from those that can be replaced, since the meaning of the concept is in the use of a particular substance, and not its alternatives. Fuels, raw materials, some energy options can be replaceable.
Sun
It is worth starting to list natural inexhaustible resources from this species. The sun is an incredible accumulation of energy that it radiates into space every day. The amount of it that per day falls on the surface of the planet exceeds human needs by tens of thousands of times. However, people still use it very little. It should be borne in mind that the sun emits several types of radiation - direct and diffuse. Modern batteries can perceive different options. For example, a thermal solar installation that can heat water uses both types of radiation, converting energy even in cloudy weather. A photovoltaic plant generates electricity. For her, the weather turns out to be more significant - you need to connect the battery so that in the cloudyday, the energy gradually accumulated too.
Wind
Some derivatives of the previous type of energy also belong to inexhaustible natural resources. Wind occurs as a result of uneven heating of the Earth's surface. Solar energy is converted into air movement. People began to use the wind already several millennia ago - in navigation. A little later, mills were invented, the blades of which also move air. Kinetic wind energy is available almost all over the planet and is extremely attractive for the environment, as it does not create waste and emissions into the atmosphere. In addition, this source is worth nothing. It can be used both privately and on an industrial scale. Since the 70s, various experiments have been carried out to create the most efficient wind pumps that would create electricity. At the moment, the number of such devices is quite large in the United States of America and European countries such as Holland, Denmark, Germany.
Tides
The inexhaustible natural resources also include the forces of the waves of the seas or oceans. The energy of water has been attracting people since the early Middle Ages, when people tried to create dams and learned how to make grain mills located on the banks of the river so that the blades were rotated by the current. The first such device appeared already in the eleventh century. Similarly, energy was used in sawmills. With the advent of the needin electricity the picture has changed. The importance of energy is growing. So it occurred to man to use natural inexhaustible resources to create it, and the first tidal power plants appeared. A dam is located at the mouth of a river that flows into the sea or ocean. It blocks the flow of water, which makes huge turbines rotate. They are connected to a generator that creates electricity. This system works only during high or low tide, but it also allows you to get an impressive amount of energy. At the moment, this method is most developed in France.
Climate
The inexhaustible natural resources exemplified above can in some sense combine with this species. Climate is a combination of zonal light, thermal energies and radiation that create certain conditions for the life of animals and plants. As natural inexhaustible resources, climatic regions are understood in the sense of a source for recreation and agro-industry. The weather directly affects the growing season and determines the number and types of plants, and also allows the use of certain areas for tourism purposes. Climatic conditions cannot be destroyed, but deterioration can occur - for example, in the area of \u200b\u200bthe atomic explosion, life becomes impossible.
Soil
Almost all of the inexhaustible natural resources examples of which were described earlier were absolutelyunlimited. Soil infinity is relative. At the moment, the provision of the planet with this resource is high, but the deterioration of the environmental situation may stop the renewability of the land, and the situation will change. As a result of human activity, the soil undergoes qualitative and structural changes, which are often negative. As a result of growing agricultural plants, the land receives erosion, excess water and s alts, increased acidity and thus falls into disuse.
Currently, inexhaustible renewable natural resources such as soils are divided into zones where they can be found. In the tundra, the land is characterized by high acidity and a low level of humus. Podzolic soils of the temperate zone are sufficiently saturated with moisture and are characterized by a cloddy structure. In the steppes, there are chernozems, which are the most fertile type, with a maximum humus content and an optimal chemical composition for production. Serozems are at the junction with deserts and are poor in useful substances. Krasnozems are suitable for subtropical crops. Such natural inexhaustible resources need attention and constant monitoring.
