Anthropization is the transformation that human beings exert on the environment, whether on the biotope or the biomass "Biomass (ecology)"). Also an animal that permanently interacts with a human can be behaviorally anthropized.

The permanent interaction of domestic animals with humans produces certain degrees of anthropization, whether learned through repetition or through repetitive co-habitation customs. For example, a pet dog can acquire certain behaviors that emulate human behavior, walking on two legs, manipulating a doorknob or an alert button, etc. A guide dog learns to recognize traffic conditions, a monkey can manipulate a television control or a telephone. The best example in this sense are circus animals.

The term is used to refer generally to any transformation that man produces on the environment, whether urbanization, agriculture, forestry, introduction of exotic species in general, land clearing, mining, laying of cables, construction of roads "Camino (via)") and bridges, dredging of navigable waterways, construction of dams and reservoirs, etc.[1]​

Many times the great anthropization of nature is what eliminates large complex ecosystems, exterminating species and generating loss of biodiversity and balance on the planet. Today we can see the devastating consequences of extreme cases of anthropization such as the gigantic deforestation of the Amazon, the hydroelectric plants (dams) that cut the river in two, thus dividing many species, this also includes large cities that grow and grow, thus invading places where rich ecosystems previously existed. Thus taking away space from the wild nature that had enveloped the entire planet Earth in the centuries, millennia and tens of millennia of the past.
