Agricultural pollution is an anthropogenic phenomenon, which consists in the accumulation of an excessive amount of harmful substances in soils and waters, pollution of the biosphere as a result of the use of unsustainable methods of agriculture and animal husbandry, and disruption of the ecosystem. Even though compared to industry and transport, the agricultural sector affects nature to a much lesser extent, there are several environmental problems directly related to agriculture: 1) Among the main problems of agriculture, one can single out, first of all, the fact of plowing huge territories and deforestation for fields and hayfields. When the natural vegetation layer is removed, the soil structure begins to change, weathering of the fertile layer and dehydration occurs since the plants cease to retain groundwater. 2) The use of chemicals for fertilizing, increasing yields, destroying pests in large doses contaminates the soil and leads to the accumulation of harmful substances not only in the earth itself but also in those plants that grow on this land, as well as in meat and milk of animals, eating such plants. 3) Animal waste also does not add purity and balance to the ecological system. Besides, the digestive process of cattle is accompanied by the release of methane into the environment, which enhances the already existing greenhouse effect. 4) It is impossible to write off the emissions from agricultural machinery, which is actively used in the production of agricultural products and provides the atmosphere with its portion of exhaust gases. To neutralize or at least reduce the impact of the above factors, the following methods are useful: 1) Reducing industrial emissions. At first glance, this has nothing to do with agriculture, however, the fewer combustion products in the air, the less harmful aerosol is formed from ammonia gases. In this situation, even a slight increase in the volume of nitrogen compounds in the air will be permissible - the main thing is that they have nothing to react with. 2) Use of natural fertilizers in reasonable dosages. This method may seem unprofitable since it is much more difficult to achieve the same impressive yields on purely natural fertilizers than on "chemistry". However, the cost of environmentally friendly products has been increasing recently due to their demand, and this method of farming may well be profitable. 3) Destruction of pests without chemicals. Science does not stand still, and new ways are emerging to ward off unwanted "visitors" to fields. The most popular method today is using ultrasound. It allows you to scare away harmful insects without harming the plants. 4) Competent work with waste. High-quality neutralization of agricultural products is an important step towards preserving the environment without sacrificing productivity. Filtration and disinfection of effluents, cleaning of soils, preservation of forests as natural filters - all this will reduce the level of agricultural pollution of the environment. Through joint efforts and the introduction of appropriate measures, we will be able to solve the problem of environmental pollution through agricultural activities. Therefore, we must develop and promote solutions to this problem! |
