Natural inexhaustible resources: species, examples

Some of the riches of the earthly subsurface that a person uses every day exist in a limited number. If the use of alternative substances is not proposed, sooner or later they will end and related production will be impossible. In order to understand the prospects of the industry and the ecology of the planet, it is worthwhile to understand what natural resources are and which of them can be used without restrictions.

Main classification

Natural resources are the natural resources used by human society for the economy. As a rule, they are classified based on the origin. According to this division, in the first place are allocated soil. Then it is worth to call the forest and water. No less important are biological resources. Mineral resources are mineral raw materials. There are also energy and climate. Exhausted and inexhaustible natural resources are not included in this classification. Almost every type has a direct relationship with each other.

Classification by exhaustibility

So, the basic types are studied. It is necessary to understand with what there are exhaustible and inexhaustible natural resources specifically. To determine each variant of wealth to a particular type, it is necessary to pay attention to its renewability. This is a complex concept, since many species have limits of exhaustion, beyond which it ceases to recover. Nevertheless, the main renewable resources can be called forests, water, soil, as well as wind, currents, sun and climate. It is also worthwhile to separate the classification by substitutability. Types of inexhaustible natural resources are different from those that can be replaced, since the meaning of the concept is the use of a particular substance, not its alternatives. Replaceable can be fuel, raw materials, some energy options.

The sun

It is worth starting to list the natural inexhaustible resources from this species. The sun represents an incredible accumulation of energy, which it radiates daily into space. That its number, which per day falls on the surface of the planet, exceeds human needs tens of thousands of times. Nevertheless, people use it very little. It is worth considering that the sun radiates several types of radiation - direct and scattered. Modern batteries can take different options. For example, a thermal solar installation that can heat water uses both types of radiation, converting energy even in cloudy weather. The photovoltaic system creates an electric current. For her, the weather is more significant - you need to connect the battery, so that on a cloudy day the energy is gradually accumulated, too.

Wind

To inexhaustible natural resources are some of the derivatives of the previous type of energy. The wind arises as a result of uneven warming up of the Earth's surface. Solar energy is converted into air movement. People began to use the wind several thousand years ago - in navigation. A little later, the mills were invented, the blades of which also move the air. The kinetic energy of the wind is available almost all over the planet and is extremely attractive to the environment, as it does not create waste and emissions into the atmosphere. In addition, this source is worthless. It can be used both privately and on an industrial scale. Since the 70s, various experiments have been conducted 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 in such European countries as Holland, Denmark, Germany.

Tides

The inexhaustible natural resources include the forces of the waves of the seas or oceans. The energy of water has attracted people since the early Middle Ages, when a man tried to create dams and learned to make grain mills located on the river bank so that the blades rotated the current. The first such device appeared in the eleventh century. Similarly, energy was used in sawmills. With the advent of the need for electricity, the picture has changed. The importance of energy increases. So it occurred to man to use natural inexhaustible resources for its creation, and the first tidal power plants appeared. At the mouth of the river, which flows into the sea or ocean, a dam is located. It blocks the flow of water, which makes huge turbines spin. They are connected to a generator that generates electricity. This system works only during high tide, but it also gives you an impressive amount of energy. At the moment, this method is most developed in France.

Climate

Inexhaustible natural resources, the examples of which were given above, can in some sense unite with this variety. The climate is a combination of zoned light, thermal energies and radiation, which 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 vegetation period and determines the number and types of plants, and also allows the use of certain territories for tourist purposes. Climatic conditions can not be destroyed, but deterioration may occur - for example, in the field of nuclear explosion, accommodation becomes impossible.

The soil

Almost all of the inexhaustible natural resources, examples of which were described earlier, were absolutely unlimited. The infinity of the soil is relative. At the moment, the security of the planet with this resource is high, but the deterioration of the ecological situation can stop the renewability of land, and the situation will change. As a result of human activity, the soil tolerates qualitative and structural changes, which are often negative. As a result of growing agricultural plants, the land receives erosion, excess water and salts, increased acidity and thus goes out of use.

At the moment, such inexhaustible renewable natural resources, like soils, are subdivided into zones where they can be found. In the tundra, the earth is highly acidic and has a low level of humus. Podzolic soils of the temperate belt are quite saturated with moisture and are characterized by a lumpy structure. In the steppes there are chernozems, which are the most fertile type, with the maximum content of humus and the optimum chemical composition for production. Serozems are at the junction with deserts and are poor in useful substances. Red earths are suitable for subtropical crops. Such natural, inexhaustible resources need attention and constant control.
