For millennia, man has influenced the environment to one degree or another, adapting it to his needs. Over time, nature began to lose its original appearance, turning from a temple into a workshop or experimental laboratory. Unfortunately, in most cases, the impact of a person on the world around them leads to negative consequences.

Step 1

Human influence on nature can be direct and indirect. The direct impact of anthropogenic factors takes place, for example, when plowing virgin lands, erecting hydraulic structures, laying highways and other communications. In many cases, such changes irreversibly destroy the familiar landscape, transforming nature.

Step 2

The indirect impact of civilization on the environment is also widespread. An example is the active combustion of fuel in the course of production activities. In this case, the person himself does not directly interact with biological organisms, but the products of fuel combustion enter the environment, leading to atmospheric pollution and negatively affecting plants and animals.

Step 3

A person in his activity very often changes nature in a spontaneous, unconscious way, not wanting it. Even an ordinary walk in the woods or a picnic in the countryside can be destructive for plants and living organisms. People trample grass, pluck flowers, step on small insects. The worst thing is when garbage remains uncleaned at the place of a picnic or a resting place for tourists, which not only spoils the appearance of the area, but also has a detrimental effect on nature.

Step 4

A much larger-scale impact on nature is exerted by purposeful human activity. Civilization for its existence needs the cultivation of vast tracts of land. By cultivating fields for growing cereals, people are making changes in nature that are permanent and often irreversible. Agricultural activity can completely change the ecology of significant areas. At the same time, the structure of the soil changes, some species of plants and animals are displaced.

Step 5

The impact of man on nature is felt to the greatest extent where population density is high, for example, in large cities and their environs. Every day people have to solve issues related to the provision of energy and food, disposal of industrial waste and waste products. And most often such problems are solved at the expense of nature and to its detriment. An example is the colossal landfills of household waste, which are arranged on the outskirts of megacities.

Step 6

Human impact on nature can also be positive. For example, in order to preserve rare and endangered species of plants and animals, nature conservation areas, reserves, wildlife sanctuaries and national parks are being organized in certain states. Economic activity is usually prohibited here, but effective preventive measures to preserve natural diversity are carried out quite widely.
