The birth of the word 'nature' as we know it now came from the Latin dictionary from 'natura'. This word in turn found its basis from 'physis' from the vocabulary of the Greek language which broadly means an understanding of all things living around us, including the living as well as the nonliving but that which was continually adjusting to the changes occurring in our surrounding, our world as we call it now.
Our world, as we have referred to primarily compromises of our home, our planet, named 'Earth'.Earth forms a small part of the solar system of our galaxy, we call the milky way. The uniqueness of our planet is its ability to be able to sustain all sorts of life forms, these includes life forms on land, air and water. The primary reason for this is its positioning in the solar system where in it lies extremely close to the sun, third, precisely but neither too close to burn out all life forms owing to the excessive heat emanated from the sun, nor too far to freeze all life forms and doom this planet into subzero freezing temperatures unable to sustain any life forms.
Earth is an extremely large planet and showcases a variety of temperature zones, climatic condition, natural habitats which vary from the tropics to the equator to the two poles or hemispheres as we know them. About 70% of this planet is fluid, occupied by water thus giving a wide range of species to survive and thrive.
Over the past few billion years since the existence of this planet, it has seen various changes, namely atmospherically, geologically and structurally. The environment was an extremely acidic one as the Earth was in its primitive years, this was unstable and unsuitable for major lifeforms as both, the air as well as the water contained extremely high amounts of toxic gases, such nitrogen dioxide, carbon dioxide, sulphur dioxide in extremely high percentage, this being extremely deleterious to the survival of life forms. Land masses were extremely unstable and were more like semisolid lava that emanated from the core of the earth, no proper land formations, or continents as we know them today were present. During this phase, the first life form or what we constitute as basis of nature were formed as electrically charged single and double molecules of various elements that combined to give birth to the first 'life forms'.
As the years passed and climatic conditions began to settle down to a much more neutral environment, these single and double elemental organisms eventually began to combine, multiply, develop and eventually evolve to bigger and more complex micro-organisms. These early micro-organisms were called as Plankton's and were present for at least a few billion years. By now, the lava on the land masses had begun to cool and form what we call the 'crust' of the earth, the land masses which began to form the very basis of life on land, what we call as flora and fauna. The condensation helped give moisture to these land surfaces that were formed thus only making them more fertile to support life in its basic forms. Billions of years later, the land masses separated, then rejoined and then again separated to form what we know as our continents today. The water bodies also stabilized to form a neutral and an environment friendly towards creating, harboring, and nurturing life in various forms. This thus forms what we call the 'Geological' evolution of earth.
Nature and Geology go hand in hand since both complement and are necessary for survival of each other. Any damage to nature has an adverse effect on our geology and our geological evolution has helped to support and flourish our natural habitat.
By this time, plankton was abundant in number and was only evolving to form more complicated life forms. The geological landscape of earth boasted of millions of years of lava sedimented over one another, this lead to the deposition of certain oils, minerals, natural substances that would eventually help mankind as and when it evolved. Deposition occurred into various rock surfaces at different levels forming various types of rocks, e.g. Bacolith, lacolith, crystals etc. These substances would form the basis of modern-day medication and contents of modes used to treat illnesses and diseases naturally.
The atmospheric conditions also stabilized and there was abundance of oxygen and nitrogen in the air to support all forms of life. Along with these gases were present many other gases, but in smaller percentages. Water vapour has been an essential ingredient in our atmosphere that has given rise to many a meteoric condition, especially rain and ice, whichever would be required ranging from the conditions of climate as well as location of respective places on the Earth. The earth was protected by the harmful rays of the sun, namely the ultraviolet rays which could destroy and prove to be harmful to life forms, by the formation of a dense layer of ozone, which would neutralize the ill effects of the same, this protective layer around the earth came to be known as the ozone layer.
The ozone layer plays an extremely important part especially today, billions of years later from its formation when it helps check and keep under control green house gases and also helps control radiation from the sun, known to be a primary cause of skin cancer in a large section of our population presently.
Presence of water leads to the formation of major water bodies, majorly forming the oceans as we know them now. Within and, there were lakes, ponds and rivers that would connect the smaller water bodies to the oceans.
The trio of neutral atmospheric conditions, water, and land lead to the development of an 'eco system' which is more like a self-sufficient model for flourishing and thriving of life forms. It is here, in the earliest eco systems that plants, and animals were born, thus giving meaning to the expression called 'life'. Evolution then took over and simple forms of life began to replicate and multiply to form complex and more intelligent life forms, these included bacteria, fungi, algae, microbes, insects, and fish or aquatic life forms. It is thus, that life forms spread its tentacles into various forms, each unique in its own manner and capable of surviving on its own under the umbrella of a common ecosystem without hurting or causing harm to it or to any other organism.
Billions of years later, or present day as we know it, life is divided into the plant and the animal kingdom. These are further sub divided into various categories depending on their appearance, origin, manner of living etc.
As evolution further continued, various species were able to adapt to a variety of climatic circumstances available, which included the freezing Polar Regions, to the hot sub Saharan deserts to the tropical humid climate and were able to establish themselves and continue prospering.
Animal life, as we know it, is more dependent on food externally to process and synthesize basic requirements for functioning and stability of the organism. Plants, on the other hand are self-sufficient and majority of them derive their energy from the sun, converting it into food to nourish and facilitate growth. This explains to us that plants as well as the animals are interdependent on one another as well as their surroundings for survival; this forms a delicate balance in the eco system which is essential for the existence for all organisms.
The importance of understanding how we came into existence is thus very necessary because all basis of any sort of treatment, whether natural or artificial are derived from resources provided to us by nature. Modern medicine derives its sources of understanding to biochemistry, specifically in case of medicines made from plants. This is also applicable to modes of treatments made use of during the Chinese Era as well as Ayurvedic period which inculcated the use of plants for treatment purposes. Modern day antibiotics owe their existence to microbes, Alexander Fleming discovered Penicillin, the first antibiotic from a bacterial sample! It is thus important to know how our so called 'nature' has come into existence and how it forms the basis of what we have derived towards methods of healing and treating as we know and use today.
