Why is human activity identified as a special environmental factor?

The anthropogenic factor should be highlighted, since, in comparison with other species, a person has a significant impact on the environment, not only direct (destruction of animal species as a result of hunting and plant species), but also indirect (changes in the landscape, climate, chemical composition of the atmosphere, ponds and soil, structures of the upper layer of the earth, the accidental spread of parasites and pests, drainage of swamps, and so on). In addition, the consequences of activity are irreparable and irreversible, which cannot be said about biotic factors.
