The relationship between the man and the environment has been established in the early periods itself. Human beings live in the kingdom of nature and interact. Man- Environment Relationship Regulator of natural erosion; Protecting the ground from raindrop; Absorbing runoff Relationship between SC and Env.

Relationship between agricultural production, settlement patterns, socio-political system and.

Unforeseen paradoxes have arisen in the man-nature relationship. One of them is the paradox of saturation. For millions of years the results of man's influence on nature were relatively insignificant. The biosphere loyally served man as a source of the means of subsistence and a reservoir for the products of his life activity. The contradiction between these vital principles was eliminated by the fact that the relatively modest scale of human productive activity allowed nature to assimilate the waste from labour processes.

But as time went on, the growing volume of waste and its increasingly harmful properties destroyed this balance. The human feedback into nature became increasingly disharmonised. Human activity at various times has involved a good deal of irrational behaviour.

Labour, which started as a specifically human means of rational survival in the environ ment, now damages the biosphere on an increasing scale and on the boomerang principle—affecting man himself, his bodily and mental organisation. Under the influence of uncoordinated production processes affecting the biosphere, the chemical properties of water, air, the soil, flora and fauna have acquired a negative shift. Experts maintain that 60 per cent of the pollution in the atmosphere, and the most toxic, comes from motor transport, 20 per cent from power stations, and 20 per cent from other types of industry.

It is possible that the changes in the chemical properties of the biosphere can be somehow buffered or even halted, but the changes in the basic physical parameters of the environ ment are even more dangerous and they may turn out to be uncontrollable.

We know that man can exist only in a certain range of temperature and at a certain level of radiation and electromagnetic and sound-wave intensity, that is to say, amid the physical influences that come to us from the atmosphere, from outer space and from the depths of the earth, to which we have adapted in the course of the whole history of the development of human life.

From the beginning man has existed in the biosphere, a complex system whose components are the atmosphere, the hydrosphere, the phytosphere, the radiation sphere, the thermosphere, the phonosphere, and so on. All these spheres are and must remain in a natural state of balance. Any excessive upsetting of this balance must be to the detriment not only of normal existence but of any existence at all, even human vegetation.

If humanity does not succeed in preventing damage to the biosphere, we run the risk of encountering the paradox of replacement, when the higher plants and animals may be ousted by the lower. As we know, many insects, bacteria, and lichens are, thanks to their relatively simple structure, extremely flexible in adapting to powerful chemical and even physical factors, such as radiation. Mutating under the influence of an unfavourable environment, they continue their modified existence.

Man, on the other hand, "nature's crown", because of the exceptional complexity of his bodily and mental organisation and the miraculous subtlety and fragility of his genetic mechanism may, when faced with a relatively small change in the chemical and physical factors of the environment, either produce unviable progeny or even perish altogether. Another possible result of harmful influences on the environment is that the productivity of the biosphere may substantially decline.

Already we observe unfavourable shifts in the great system of the universe: Much more carbon dioxide is being produced on earth than plants can assimilate.

Man and Environment: Essay on Man and Environment

Thus, not only progress but even human life itself depends on whether humanity can resolve the paradoxes in the ecological situation that have arisen today. Modern technology is distinguished by an ever increasing abundance of produced and used synthetic goods. Hundreds of thousands of synthetic materials are being made.

People increasingly cover their bodies from head to foot in nylon, capron and other synthetic, glittering fabrics that are obvious ly not good for them. Young people may hardly feel this and pay more attention to appearance than to health. But they become more aware of this harmful influence as they grow older.

As time goes on the synthetic output of production turns into waste, and then substances that in their original form were not very toxic are transformed in the cycle of natural processes into aggressive agents. One gets the impression that human beings are working harder and harder to organise bits of synthetic reality by disorganising the systems evolved by nature.

Emphasising man's hostility to nature—a hostility armed with the vast achievements of modern technology—both natural scientists and philosophers are today asking themselves the pessimistic question: Is it not the fatal mission of man to be for nature what cancer is for man himself?

Perhaps man's destruction of the biosphere is inevitable? One would like to think that the limited capacities of nature do not signify a fatal limitation of civilisation itself. The irrational principle, which once permeated human nature, still exists in human behavioural mechanisms, as can be seen, for instance, in the unpredictable consequences of their individual and concerted efforts.

Much in human activity goes beyond the limits of the predictable, even when it is humanely oriented. The man-nature relation, the crisis of the ecological situation is a global problem. Its solution lies in the plane of rational and humane, that is to say, wise organisation, both of production itself and care for mother nature, not just by individuals, enterprises or countries, but by all humanity, linked with a clear awareness of our planetary responsibility for the ecological consequences of a civilisation that has reached a state of crisis.

One of the ways to deal with the crisis situation in the "man-nature" system is to use such resources as solar energy, the power of winds, the riches of the seas and oceans and other, as yet unknown natural forces of the universe. At one time in his evolution man was a gatherer.

He used the ready-made gifts of nature. This was how human existence began.

Perhaps even today it would be wise to resort to this method, but on a quite different level, of course. The human being cannot restrict himself to gathering, any more than he could in primitive times. But such a shift in attitude could at least abate the destructive and polluting principle in civilisation. As cybernetic methods and principles in the various fields of knowledge and practice develop, control theory has been widely applied in many spheres.

Its aim is to ensure the optimal function of a system. A humanely oriented mind should be able to transfer the idea of optimality and harmony to ecological phenomena. In their production activity people are mastering more and more new materials and learning to replace one with another.

In the long term this could lead, as the alchemists once believed, to production on the principle of everything out of everything. Moreover, our planet has an active balance—it loses less substance in the upper layers of the atmosphere than it receives from outer space. It would therefore appear that the amount of substance available as a whole will not place any radical limitation on material production.

Life, including human life, is not only metabolism; it is also a form of energy transformation and movement developed to degrees of subtlety that are as yet beyond our comprehension.

Man and Society

Every cell, every organ and organism as a whole is a crucial arena of the struggle between entropic dispersing and anti-entropic processes, and the biosphere represents the constant victory of life, the triumph of the anti-entropic principle in the existence of the living. Losses of living energy from our organism are constantly compensated by various forms of energy flowing from the vast expanses of the universe.

We need not simply energy, such as electromagnetic radiation or heat, but radiant energy of the finest quality. The struggle for the existence of living creatures, including man, is a struggle not so much for the elements that compose his organism—they are abundantly available in the air, water and underground—not for solar energy in its direct, electromagnetic radiation, but for the energy that is captured by the mechanisms of photosynthesis and exists in the form of organic, particularly plant structures.

When we consume vegetable food, we take the energy of nature, particularly that of the sun, at first hand, so to speak. But plants are also the food of herbivorous animals, and when we eat meat, we take this energy at second hand. So the biosphere is not a chaotic conglomeration of natural phenomena and formations.

By a seemingly objective logic everything is taken into account and everything mutually adapts with the same obedience to proportion and harmony that we discern in the harmonious motion of the heavenly bodies or the integral paintings of the great masters.

With a sense of wonder we see revealed before us a picture of the magnificent universe, a universe whose separate parts are interconnected by the most subtle threads of kinship, forming the harmonious whole which the ancient philosophers surmised when they viewed the world with their integrating, intuitively perceptive gaze. We are part of the ecological environment and it is a part of the universe. It contains myriads of stars and the nearest of them is the Sun.

The Sun is the master of Earth. We are, in a certain sense, its children. Not for nothing did the rich imagination on whose wings mankind flies ever further and higher in the orbit of civilisation portray the Sun in ancient legends as the highest deity. But to return to our theme, the bitter truth is that those human actions which violate the laws of nature, the harmony of the biosphere, threaten to bring disaster and this disaster may turn out to be universal.

How apt then are the words of ancient Oriental wisdom: Puts tremendous pressure on the natural resources and environmental quality. This is due to the fact that population growth leads to poverty which directly or indirectly declines the environmental standard.

Rational use of non polluted water resources: The restoration of water quality of our water bodies and their optimum uses are the challenges before the present society.

To sustain and increase agricultural growth: The over cultivation of soil, results in nutrient deficiency, lack of organic matter, soil salinity and damage to physical structure of the soil. To check soil erosion: The soil erosion can be prevented by the restoration of land or soil resources which are directly or indirectly related to strategies for the management of land, water and forest. Restoration of forest resources: The forest resources are depleting at a very faster rate in order to meet growing need of timber and farmland for the increased population.

Vast forest areas have been converted into barren waste lands. So it is the need of the present society to restore our forest resources possibly through social forestry and afforestation programmes. The overexploitation of natural resources, intervention of bio-geochemical cycles and trace element cycle, extraneous release of matter and energy etc. In addition, continuous green house gas emission, hazardous chemicals of industry and agriculture, nuclear arsenals; radioactive wastes and biotechnological misuse lead to global catastrophism.

So the prevention of pollution is of prime importance for the present society. Considering the above issues, it is clear that the fate of human being depends on how he is managing and overcoming the above problems.
