Over the past several millennia, human activity has caused little damage to the environment, but after the technical revolutions, the balance between man and nature was disrupted, since since then natural resources have been intensively used. Soil has also been depleted as a result of agricultural activities.
Regular farming, growing crops leads to land degradation. Fertile soil turns into a desert, which leads to the death of human civilizations. Depletion of the soil occurs gradually and the following actions lead to it:
- heavy irrigation contributes to salinization of the soil;
- loss of organic matter due to insufficient fertilizer;
- excessive use of pesticides and agrochemicals;
- irrational use of sown areas;
- random cattle grazing;
- wind and water erosion due to deforestation.
The soil is formed for a long time and is restored very slowly. In places where cattle graze, plants are eaten away and die, and rainwater erodes the soil. As a result of this, deep holes and ravines can form. To slow down and stop this process, you need to relocate people and animals to other areas and plant a forest.
In addition to the problem of erosion and depletion due to agriculture, there is another problem. This is soil pollution by various sources:
- industrial waste;
- oil spill;
- mineral fertilizers;
- transport waste;
- construction of roads, transportation hubs;
- Urbanization processes.
This and much more causes soil destruction. If you do not control anthropogenic activities, then most of the territories will turn into deserts and semi-deserts. The soil will lose fertility, plants will die out, animals and people will die.
