Classification of Ecological Problems of the Earth associated with disorders of the components of the landscape, conventionally divided into six categories: - atmospheric (thermal, radiological, mechanical or chemical pollution of the atmosphere); - Water (contamination of the oceans and seas, as the depletion of groundwater and surface water); - Geological and geomorphological (activation of negative geological and geomorphological processes, strain relief and geological structure); - Soil (soil contamination, salinization, erosion, deflation, waterlogging, and so on. N.); - Biotic (vegetation degradation and forest, reducing species diversity, pasture digression, and so on. D.); - Landscape (complex) - the deterioration of biodiversity, desertification, the failure mode of an established protected areas and so on. N.
