Problems of the Present: Soil Contamination and Depletion

From time immemorial, land resources were considered oneof the most important types of wealth. Nevertheless, at present, the soil cover accounts for a considerable load. In the following material, one of the most important problems of our time will be considered: land pollution.

Soil contamination and depletion

Main reasons

Soil pollution and depletion nowis a special type of land resource degradation. At the same time, 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, because of the movement of lithospheric plates, the constant impact of significant air masses or water elements. In connection with all the above reasons for natural destruction, the hard shell of the Earth gradually changes its appearance. As the second factor, as a result of which pollution and depletion of soil occurs, one can call anthropogenic impact. Currently, it is the one that causes the greatest damage. Consider this destructive factor in more detail.

Human activities as the cause of soil degradation

Negative anthropogenic impact is oftenarises as a result of agricultural activities, the work of large industrial facilities, the construction of buildings and structures, transport communications, as well as household needs and the needs of mankind. All of the above is the cause of the negative processes, called "Pollution and depletion of soil." Among the consequences of the impact on the land resources of the anthropogenic factor, the following can be named: erosion, acidification, structure breakdown and composition change, mineral base degradation, waterlogging or, conversely, desiccation, dehumification, and so on.

Soil pollution and soil depletion ways to solve


Perhaps, it is this kind of anthropogenicactivities can be considered key in the issue of what causes pollution and depletion of the soil. The reasons for such processes are often related. For example, first there is an intensive development of lands. As a result, deflation is developing. In turn, plowing is capable of activating water erosion processes. Even additional irrigation is considered a negative factor of impact, as it is the cause of salinization of land resources. In addition, pollution and depletion of soil can occur due to the introduction of organic and mineral fertilizers, unsystematic grazing of farm animals, destruction of vegetation cover and so on.

Chemical pollution

The soil resources of the planet are significantly influencedis on the part of industry and transport. It is these two directions in the development of human activity that lead to the contamination of the earth with all sorts of chemical elements and compounds. Heavy metals, oil products and other complex organic substances are considered especially dangerous. The appearance of all of the above compounds in the environment is associated with the operation of industrial plants and internal combustion engines that are installed in most vehicles.

Soil contamination and depletion: ways to solve the problem

Of course, it is necessary initiallyeach person understood the extent of his responsibility for the favorable ecological situation on the planet. In addition, even at the legislative level, it is necessary to establish restrictions on the conduct of economic activities. An example of such measures can be considered an increase in green spaces, as well as the establishment of control and systematic checks of rational land use.
