As a person changed Earth

As someone has changed the Earth

Human impacts on the environment and the Earth as a whole is called the anthropogenic impact.

Change the world by humanactivities took place for decades and even centuries, so it is necessary to understand how the man has changed the Earth and how this change took place, depending on the milestones of human development.

Milestone 1. Primitive communal system of society.

This stage of development of human societyborn about 50 thousand years BC. Man has learned to use the gifts of nature is reflected in the fact that he has mastered the first gathering, and then hunt. Gathering means that the person is able to distinguish between the different grass, berries, mushrooms and other natural materials and use them without any preprocessing, just collecting them from their natural environment. The meaning of the hunt was the fact that by means of capture or killing using skins, furs and meat animals. Anthropogenic impact was minimal. The man was still forced to adapt to the wild environment, since it represented a serious danger for him.

Milestone 2. The emergence of agriculture.

Agriculture originated in what is nowTurkey about 12,000 years ago. First cultivated wheat crop began. Today, agriculture involves a myriad of diverse cultures, the majority of which was obtained by selection of existing species. From the point of view of human impact, agriculture has had an enormous influence on the Earth. To maintain its specially treated soils, apply artificial and modified natural irrigation systems, forests are cut down, covered or dried lakes and marshes.

It was at this time mankind began to engage inanimal husbandry. Even without knowing the meaning of the word "selection", people have learned to withdraw, and cross the most suitable for the further use of animals (horses, cows, etc.).

Milestone 3. Processing of natural materials.

By the time the first major countries tothe south-east Asia, North Africa and the Mediterranean man has learned to smelt metals, processed stones, wood and other materials, bestowed by nature. Built palaces, houses, roads. The man began to realize his position in this world, so that the development of society has undergone dramatic changes.

Milestone 4. Middle Ages.

This era is characterized, first of all, notas rapid technological 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 develop its available natural resources. However, the above does not mean that the era of the Middle Ages equivalent of stagnation. Continued to develop the country and the state, forms the new trade routes, the man continued development of previously inaccessible corners of the earth for him.

Milestone 5. New Time.

This era was marked by a new look atand Earth environment in general. Now people realize themselves as the center of the world. This resulted in the fact that the new time has been a period of great scientific achievements in all spheres of human activity. This qualitative and quantitative impact on the human impact on the Earth. The era of the great geographical discoveries that led to that person became available previously unknown plants, animals and materials. It began active development of production of various products. With the advent of advanced manufacture production can speak with confidence about the birth of mass consumption. This led to an increase of natural resources consumed by humans.

The new time is also associated with an activeChurch of resistance to various new and heretical (from their perspective) ideas. It is because their actions have been brought to the Inquisition such great scientists as John. Bruno and Galileo Galilei.

Milestone 6. Contemporary XX Century.

Scientific and technological revolution, which occurredthanks to the invention of a new sample loom and "martin" metallurgical furnace in the second half of XIX century., led to the emergence of mass production. It has spurred the development of capitalism, which could not but affect the processes of globalization. Earth began to envelop the transport network on the world map, new town, new types of industries appeared and evolved. The planet had become the cloth on the ground, which can be infinitely meet human resource requirements. Such barbaric attitude to the planet could not but affect her condition. Phenomena such as pollution, global warming and changes in global sea level, do not go to the mouth of environmentalists around the world.

Milestone 7. XXI century - the time of the error awareness.

In this century mankind has realized that it is notYou can always use the earth as a source of resources, in fact most of them - non-renewable. Human eyes rushed to the alternative sources of energy, restore the subsurface resources. Latest technological inventions mostly connected not with the intensive development of production and optimization of material handling processes have previously created. The information society demands a more and more new ways to different speed of data exchange. Form a society looked to the earth, not as a source of resources, as well as the house, behind which needs constant care, attention and care.
