Modern man, especially urban dwellers, at first glance, does not depend much on the nature. It is surrounded by neat heated homes, factories; transport moves the asphalt streets; River encased in granite; little greenery. Even in rural areas to housing looms plowed fields and woods sometimes turns blue only on the horizon. But it is misleading. All around us: the structure and machinery, food and consumer goods, raw materials, on which we are working, finally, the energy that consumes a person (whether muscular or mental energy or energy driving the powerful machine) - all this people draw nature of the bins. However, in the labor process the original form, composition and properties of many natural bodies and objects sometimes changed beyond recognition. But in a modified form it is easy to establish that they are made from plant, animal or mineral raw materials.Even clearer connection with nature in cultivated fields, crop plant or pet - their people changed relatively little, turning it into a controlled source of raw materials and food.But the nature of man is not only a source of food and raw materials for industrial processing. The man - part of nature itself - needs in a supportive environment and life with clean water and air; in recreational areas with beautiful landscapes, among which the most well-restored mental and physical strength; in the pristine expanses of hunting and tourism. Scientists consider it necessary to keep all wild plants and animals as a material for introduction to the culture and domestication or hybridization. In addition, engineers are naturally much that they can move in the technique. It is necessary to use nature so that it does not lose all of its useful and necessary for human qualities.
Everything on our planet is interconnected. Nature provides us with lots of products, which are indispensable to human existence and of our relationship to natural resources depends the future of all life on Earth.
The increasing globalization leads to the fact that many of the processes occurring in the nature, and its problems caused by both human activities and natural events, from the local become international. Fewer still on the Earth groups, which do not affect the dramatic environmental changes.
The most important problem of the 21st century is environmental pollution. Development of technologies to improve our quality of life has its downside: there is a pollution of the environment, harms not only by humans but also animals and plants, which eventually leads to the impoverishment of fauna and flora diversity, and even the complete disappearance of many species.
Environmental pollution does not respect borders: it is impossible to build a stone wall, or put a customs posts along the entire state border protection streams contaminated air and water masses, and other carriers of dangerous pollutants.
Nature IS NOT an object, existing separately from people; nature is us; we are an integral part of and should take care of it the best way. This is the solution of problems of environmental contamination.
Human impact on the environment
Scale created by mankind material culture are immense. And the pace of its development are constantly increasing exponentially. Nowadays, the so-called tehnomassa (ie, all that man has created for the year ) is an order of magnitude greater than the biomass (weight of wild living organisms ), respectively 1013 tons / year in 1012 and t/year
This is a disturbing signal about the need thoughtful consideration to the balance components of the system "nature - Biosphere - man."
Level of human impact on the environment is largely determined by the level of technical equipment of society. She was very low in the initial stages of human development. However, in the future, with the growth of its productive forces, the situation began to change dramatically dramatically. The twentieth century - a century of scientific and technical progress. Associated with a qualitatively new relationship between science, engineering and technology, it is enormously increased the magnitude of the impact of society on nature and mankind has set a number of new, very serious problems.
By analogy with the " living matter " underlying the biosphere, we can talk about tehnoveschestve as the aggregate of all existing technical devices and systems ( original technocenosis ). Structure tehnoveschestva now seen from different perspectives. Thus, in one case the classification is made only of its structure similar to the structure and interaction of the components of living matter. And its membership include: firstly, technical devices, extracting the minerals and producing energy, like green plants in the biosphere ; Second, the technical unit for processing the received raw materials and production of means of production ; - third, the technique of producing means of consumption ; Fourth, technical systems for the transfer, use and storage media. In particular unit is isolated autonomous multifunctional ( robots, automatic interplanetary station, etc.). Recently, there are also utility systems for waste recycling and disposal, their inclusion in a continuous cycle of non-waste technology. This kind of "technical nurses" acting similarly biological, natural subsystems. Thus, the structure tehnoveschestva ( as a set of separate technical units and entire subsystems technocenosis ) increasingly plays a similar organization of natural living systems.
Noting the importance of art in human life, we can not dwell on the ever growing problem of humanization need technosphere. Until recently, science and technology have focused mainly on maximum exploitation of natural resources, the needs of the individual and society at any cost. Consequences of ill-conceived, and not complex, as a consequence, the dehumanizing effects on nature depressing. Technical landscapes of waste production, signs of life in the destruction of entire regions, driven into reservations nature - the real fruits of the negative impact man armed with technology on the environment. All this is also a consequence of insufficient interaction of natural and social sciences in understanding the problem.
