How a man changed the Earth</a>

The human impact on the environment and on Earth as a whole is called anthropogenic impact.

Change of the planet under the influence of humanActivity took place not for a decade or even a century, so it is necessary to understand how a person changed the Earth and how this change took place depending on the milestones of the development of mankind.

Milestone 1. Primitive-communal system of society.

This stage of development of human societyWas born about 50 thousand years before our era. Man learned to use the gifts of nature, it was expressed in the fact that he first mastered the gathering, and then hunting. Gathering means that a person is able to distinguish different herbs, berries, mushrooms and other natural materials and use them without any primary processing, simply by collecting them from the natural environment. The meaning of the hunt was to use skins, furs and animal meat with the help of catching or killing. Anthropogenic impact was minimal. The man was still forced to adapt to the wild environment, since it was a serious danger for him.

Milestone 2. The emergence of agriculture.

Agriculture has emerged on the territory of modernTurkey about 12,000 years ago. The first cultivated crop was wheat. Today, agriculture includes a huge variety of diverse crops, most of which were obtained by selecting existing plant species. From the point of view of anthropogenic impact, agriculture had a tremendous impact on the Earth. For its maintenance, specially processed soils are applied, artificial ones are applied and natural irrigation systems are changed, forests are cut down, lakes and marshes are poured or dried.

It was at this time that humanity began to engage inAnimal husbandry. Still unaware of the meaning of the word "selection", people learned to remove and cross the most convenient animals for further use (horses, cows, etc.).

Milestone 3. Processing of natural materials.

By the time the first major states appeared,The territory of southeast Asia, northern Africa and the Mediterranean Sea man learned to smelt metals, to process stones, wood and other materials, given by nature. The palaces, houses, roads were built. Man began to realize his position in this world, due to which the development of society underwent cardinal changes.

Milestone 4. The Middle Ages.

This era is typical, in the first place, notSo rapid technical development, as it was in ancient times, thanks to the progress of ancient Greece, Rome, Egypt, the Mediterranean countries and the Middle East. The man continued to master the natural resources at his disposal. But what has been said above does not mean that the Middle Ages are equivalent to the era of stagnation. Continued to develop countries and states, new trade routes were formed, the man continued to develop the previously inaccessible to him corners of the earth.

Milestone 5. New Time.

This era was marked by a new look at theThe environment and the Earth as a whole. Now the person has realized himself as the center of this world. This resulted in the fact that the New Time was the epoch of great scientific achievements in all spheres of human activity. This qualitatively and quantitatively affected the human impact on the Earth. The era of the Great Geographic Discoveries began, which led to the fact that previously unknown plants, animals, and materials became available to humans. The active development of the production of various products began. With the advent of developed manufactory production, it is possible to speak with confidence about the birth of mass consumption. This led to an increase in human consumption of natural resources.

New Time is also associated with the activeThe resistance of the church to various new and heretical (from their point of view) ideas. It was because of their actions that such great scientists as J. Bruno and Galileo Galilei were devoted to the Inquisition.

Milestone 6. The newest time and the twentieth century.

The Scientific and Technical Revolution that happenedThanks to the invention of a new type of weaving loom and the "open-hearth furnace" metallurgical furnace in the second half of the 19th century, led to mass production. This spurred the development of capitalism, which could not but affect the processes of globalization. The earth began to envelop transportation networks, new cities appeared on the world map, new types of productions appeared and developed. The planet began to perform the role of a self-cleaning tablecloth, which can unlimitedly satisfy human resource needs. Such a barbarous attitude towards the planet could not but affect its condition. Such phenomena as pollution of the environment, global warming and changes in the level of the world's oceans do not disappear from the lips of environmentalists around the world.

Milestone 7. The twenty-first century is a time of awareness of mistakes.

In our century, humanity realized thatCan forever use the Earth as a source of resources, because most of them are non-renewable. The human eye rushed to alternative sources of energy, restoring the wealth of the earth's interior. The newest technical inventions in the majority are connected not with intensive development of manufactures, and optimization of the processes of processing of materials created earlier. Information society requires itself more and more ways of high-speed exchange of various data. The formed society looked at the Earth not as a source of resources, but as a home, for which constant care, attention and care are needed.
