The types cave environment degradation under influence of anthropogenic pressure is explored: changes of cave relief state (violations of underground system’s sizes: re-equipment of natural entrances, widening of cave passages; deformations of cave sediments; presence of artificial buildings); anthropogenic rubbish (food wastes and packages, used sportive equipment; mould formed after human visits; inscriptions by paint on cave walls and ceilings); changes of air (presence of the smell); water object composition’s changes; violations of biological equilibrium; anthropogenic transformations on the surface (rubbish heaps; inscriptions by paint on cave entrances). The necessity of cave heritage preservation is at the focus of attention.
