Living organisms have not always existed on Earth; they have emerged as a result of the prolonged development of inorganic nature. In the early stages of shaping the appearance of the Earth, all living, even if it was brought from outside, would inevitably perish as a result of the lethal impact of cosmic rays. On the Earth, however, a gas coat was gradually formed, hot primate oceans appeared, and high molecular compounds were formed, including the same chemical elements as non-living nature, capable of self-complexation, decay and synthesis. That’s how life came. His main difference with non-living nature was the metabolism, constant renewal in this complex but still molecular entity.
Then came the simplest living organisms that did not yet have a cellular structure, and after a long time the one-celled and multicellular organisms appeared and differentiation of the living world of animals and plants was made.
Life and death have always gone hand in hand, they have always been interconnected and interdependent. With the collapse of living organisms, the cells and tissues composing them have broken down to their constituent elements, and then new and emerging substances have emerged and developed new living structures characterized by their selectivity with regard to the substances coming from the outside. Living organisms have only taken up their necessary “building materials”.
By the way, the qualitative distinction of the living processes from the processes in the inanimate nature is not supernatural, because the general laws of the universe are the same for both living and non-living nature. However, the specific nature of their flowing into the living environment is that the metabolism processes are reversible: after the performance of their functions, the starting materials are not completely destroyed as in the non-living nature, but they are restored to the original and even higher level.
Despite the apparent autonomy of living organisms and their organs and systems, the latter is relatively relative, with living organisms and systems being able to exist in changing environmental conditions only within certain limits, and maintaining the stability and stability of the organism is accomplished by helping of special regulation systems.
Living organisms and waste products from their metabolism have gradually begun to change the appearance of the Earth.
What are the thick layers of limestone, if not the remains of microorganisms that inhabited the Earth in ancient times? Coal is a memory of ancient tropical forests! Some ores as well as oil are also products of living organisms. For this reason, the subsequent development of the life of the Earth took place in an environment prepared by the activity of many generations of the simplest organisms of animals and plants. Moreover, the very existence of higher plants and animals would be impossible without the inferior. It was no longer necessary for them to seek their own food from the inanimate nature because it alone had prepared it for them, and thus gave them the opportunity for further evolution.
So the microorganisms have prepared the soil for the higher plants by providing them with organic substances and “building material” for the cells that have become animal feed and the dead plants and animals as well as the results of the processing of the plant food from the animals from their country, have become food for plant organisms.
Moreover, some animals have become food for others, and predatory plants have appeared, it has become possible to coexist at different levels of life, some of which have become interdependent. They all know well about lichens, which are a symbiosis between algae and a sponge, the existence of which is now unthinkable. In this sense, man is also closely related to nature, he is the product of his development, he lives in the same world in which he lives and lives, and is an integral part of the universe.
In our day-to-day activity, however, we constantly forget about it, and we believe that man as a higher being is allowed to change the world at his own discretion, although the very development of nature and all living on earth indicates that the laws of the universe can not change.
We already know what happens when these laws are not observed: the fertile valleys are turned into deserts, some species of plants and animals disappear, others occupying their place, which in most cases are weedy, harmful insects, rodents, and so on.
The need to respect the laws of nature is embedded in the very essence of living organisms, and in animals it is provided with the instincts to which they adamantly obey. However, the presence of a highly developed human brain does not allow him to blindly obey instincts. For this reason alone he was capable of self-destruction in all living nature, although in all life he must live according to the laws of nature in harmony with it. This must be understood until it is too late.
What is the normal state of the human organism, how does it express its relation and balance with the external nature? These issues are dealt with by special science – physiology that has arisen in ancient times in accordance with the needs of medicine. Indeed, how can the patient be cured and, moreover, prevent his illness without knowing the structure of the human organism and the functions of his organs? This basic condition of medicine, known to ancient physicians, is unfortunately not always taken into account by modern professionals. It is no secret that even when the “normal” parameters and symptoms that occur as a result of the deviation of the function of the organ from the normal level are present, modern medicine often does not ponder the causes of this disorder, but directs its main blow to the removal of the symptom, thereby violating one of the fundamental principles of the universe – the causal relationship.
It is known that the symptoms of most diseases include headaches, temperature rise, gastrointestinal disorders. However, this does not mean that their cause is the same. However, the treatment of radically different diseases is very often limited to prescribing painkillers and temperature-limiting agents. This, of course, alleviates the condition of the patient and can be justified to a certain extent, provided that the need for the cause itself, for example, of the headache, should not be forgotten. Raising body temperature is a sign of the organism’s struggle with an externally infected infection, with the physician’s main efforts being targeted to combat it, not the temperature that is just a symptom. It is good if the body in such treatment self-restores its normal functions with the help of its internal reserves and the capabilities of self-regulatory systems. And if he can not do it? It is then possible to develop a chronic disease and even death.
Gardeners, for example, never mind to smear ointments or to dye the yellowing leaves of the fruit tree that is in the blooming phase. On the contrary, the experienced gardener will immediately begin to cultivate the soil, water it, fertilize, and try to understand the reason for insufficient supply of nutrients, he will begin to “cure” the roots, not the crown. As a result, leaves are usually restored, the plant blooms and successfully carries fruit. In treating man, however, we instead of “curing the roots” only “crush and paint the leaves”, thus sometimes achieving its external well-being. However, man is also a child of nature, as all living on Earth and all the biochemical and physiological processes in his organism proceed in the same way as in all living things, and obey those common laws that nobody can change.
