From time immemorial, land resources have been considered one of the most important types of we alth. However, there is currently a significant load on the soil cover. The material below will consider one of the most important problems of our time: land pollution.
Main reasons
Soil pollution and depletion is currently a specific type of land degradation. There are two main reasons for such negative changes. The first is natural. The composition and structure of the soil can change as a result of global natural phenomena. For example, due to the movement of lithospheric plates, the constant impact of significant air masses or water elements. In connection with all the above causes of natural destruction, the solid shell of the Earth is gradually changing its appearance. As a second factor, which results in soil pollution and depletion, anthropogenic impact can be called. It is currently doing the most damage. Let's take a closer look at this destructive factor.
Human activity as a cause of soil degradation
Negative anthropogenic impact often occurs as a result of agricultural activities, the operation of large industrial facilities, the construction of buildings and structures, transport links, as well as domestic needs and the needs of mankind. All of the above are the causes of negative processes called "Soil pollution and depletion". Among the consequences of the impact on land resources of the anthropogenic factor are the following: erosion, acidification, destruction of the structure and change in composition, degradation of the mineral base, waterlogging or, conversely, desiccation, dehumification, and so on.
Agriculture
Perhaps, it is this type of anthropogenic activity that can be considered the key to the question of what causes soil pollution and depletion. The causes of such processes are often interconnected. For example, first comes the intensive development of land. As a result, deflation develops. In turn, plowing is able to activate water erosion processes. Even additional irrigation is considered a negative impact factor, since it is it that causes salinization of land resources. In addition, soil pollution and depletion can occur due to the application of organic and mineral fertilizers, unsystematic grazing of farm animals, destruction of vegetation cover, and so on.
Chemical pollution
On soilThe resources of the planet are significantly influenced by industry and transport. It is these two directions in the development of human activity that lead to the pollution of the earth with all kinds of chemical elements and compounds. Heavy metals, oil products and other complex organic substances are considered to be especially dangerous. The appearance of all of the above compounds in the environment is associated with the work of industrial enterprises and internal combustion engines, which are installed in most vehicles.
Soil pollution and depletion: ways to solve the problem
Of course, initially it is necessary that each person understands the measure of his responsibility for a favorable environmental situation on the planet. In addition, it is necessary even at the legislative level to establish restrictions on the conduct of economic activities. An example of such activities can be considered an increase in green spaces, as well as the establishment of control and systematic checks on the rational use of land.

Soil waterlogging: causes, possible problems and preventive measures
Soil waterlogging is considered to be an extremely undesirable phenomenon. And there are good reasons for this. Such terrain is often impassable. There are dangerous areas in them that are sucked in, and therefore many people die there. In addition, swamps are capable of igniting in the most unexpected way due to the special composition of the environment. And they are unsuitable for economic activity. But still, swamps are part of the ecosystem that brings its benefits
Monitoring soil pollution. Types of soil pollution
Humanity sometimes recklessly and cruelly exploits its planet, not noticing what consequences come from such interactions. But at the same time, the pollution of the atmosphere, soil and water in some areas of the Earth reaches critical values. About what methods exist for identifying the degree of anthropogenic degradation of the environment, as well as about measures of influence aimed at the most gentle and effective correction of the current situation, and will be discussed in the article
What is soil formation factor? What are the soil formation factors?
Earth is the we alth of all mankind. And we are talking not only about the planet, but also about the reserves of soils on its surface. Without them, there would not have been such a diverse flora, and heterotrophs (which include any animal and person) in principle could not have appeared. How did soil form on the surface of the planet? The factor of soil formation is “guilty” of this. More precisely, a whole group of them
Sources and causes of soil pollution. Types of soil pollution and consequences for the environment
Soil is a unique and priceless natural we alth. It is she who is able to provide a person with all the necessary food resources. Illiterate and careless human activities are the main causes of soil pollution
Human pollution of the soil and its consequences. Soil pollution assessment
Soil is a special natural formation that provides the growth of trees, crops and other plants. It is difficult to imagine life without our fertile soils. But how does a person relate to soils? Today, human pollution of the soil has reached colossal proportions, so the soils of our planet are in dire need of protection and protection
