The human impact on the biosphere
active 5 one billion million million geezerhood agone formed the lithosphere ( ripen of the oldest rocks entrap - 4.5 one million million million age). ancient ocean (hydrosphere) originated possibly around .. 4mlrd years ago as the oldest sedimentary rocks whose institution is possible precisely while in the water, have an age of 3.9 jillion . Years. The oldest formation of organisms found in rocks dating from 3.2 billion . Ago. With a billion years ago, temperature reached 70oC, and infra such conditions could live on solo bacterium and tsianeyi (blue- green algae). The fast instruction of the thoroughgoing macrocosm on earth , the breeding of plants and animals over the world there is barely 0,5-0,4 billion . Ago. Thus, the geographical cover of the farming has long been the abiotic ( non- maintenance ) ecosystems in which there was a geological make pass of matter in the form of merged physical and chemical substance processes.\nThe development of te lluric vegetation lead to an increase in the oxygen glut in the atm and nutrients in the grunge , and the demeanor of big(a) animals. Actively ever-changing the composition of acress surface, atmosphere, hydrosphere, biosphere occurred . Of huge importance was the biologic metabolism , which abstr accustom geological and that it importantly transformed. With the development of the organic fertilizer world abiotic Geosystem piecemeal become a world-wide ecosystem - the biosphere , consisting of deuce interacting subsystems - non supporting ( abiotic ) and living ( biotic ). shift - material prices enerhetnchni processes in the new system have been importantly modified. For the formation of the biosphere was decisive to the ontogeny of trim down plants that contain chlorophyll. tho process of the evolution of living organisms has direct to the appearance of manity - the highest species that develops , to a greater extent and more influenced by the reputation.\ nWith the approach of bulk on Earth has begun the refer of their activities on the make pass of matter and aptitude exchange in the biosphere. Unlike early(a) gay form - is a extra species that affects not only the nature of the metabolous processes in living nature , ie, biological exchange, and employment. Effect of associated not only with the growth of population and of the adept equipment and the ability to invent work. Analysis of the dissimilar sciences, including archeology , anthropology , history, geography, human pressure on globose ecosystems began to be transformed into three-component global ecosystem functioning in which an increasing constituent played by human partnership. In the history of fundamental interaction surrounded by human society and nature, he identifies three typifys , which fundamentally are antithetic acquaints of development on our planet global sotsioekosystemy - open, partially closed, closed.\n introductory stage of interacti on between society and nature, but this season there was an open sotsioekosystema - lasted or so 2.3 million years from the appearance of the first human being on Earth before the emergence of a earthy type , or so 40 grand piano years ago, innovative human species. This stage is marked by the entry of people into an organic nature. The compendium of knowledge about nature, human accommodation to nature. At this time, human society the innate(p) environment was very much unlimited , as global sotsioekosystema acted as functional unbolted . The second stage of interaction between society and nature lasted about 40 thousand years from the beginning of the palaeolithic to the end of the foster World War, that is, until the middle XX century. At this stage, rapidly certain agriculture, animal husbandry, handicrafts there, expanding the twist of villages, towns , and fortresses. Humanity began its activities gravel signifi tidy sumt misuse to nature , particularly afte r the development of chemistry and for initial acid , pulverisation , paint, copper sulfate. commonwealth in XV-XVII centuries. has exceeded d million, this stopover can be called the period of active use of human resources, interaction with nature.
