Anthropogenic factors are very diverse. By nature, anthropogenic factors are divided into:
– Mechanical – pressure from the wheels of cars, deforestation, obstacles to the movement of organisms, and the like;
– Physical – heat, light, electric field, color, changes in humidity, etc .;
– Chemical – the effect of various chemical elements and their compounds;
– Biological – the influence of introduced organisms, breeding of plants and animals, afforestation and the like.
– Landscape – artificial rivers and lakes, beaches, forests, meadows, etc.
By time of origin and duration of action, anthropogenic factors are divided into the following groups:
– Factors produced in the past: a) those that have ceased to exist, but its consequences are felt now (the destruction of certain types of organisms, overgrazing, etc.); b) those that continue to operate in our time (artificial topography, reservoirs, introduction, etc.);
– Factors that are produced in our time: a) those that act only at the time of production (radio waves, noise, light); b) those that operate for a certain time after the end of production (persistent chemical pollution, deforestation, etc.).
