Aspects of Health, Population and Environment

 Aspects of Health, Population and Environment 

Health is related to our mind, body and behavior. It is dynamic and affected by our surrounding. There are uninterrupted changes in population due to demographic components like birth, death and migration. Population is affected by both human health and environment. Environment has three major aspects. They are biotic, abiotic and abstract factors. People's health, population characteristics and environment interact with each other continuously with their mutual interinfluence. Such interaction unites three factors on the basis of the following common aspects: 

1. Physical aspect

Things around us may be living or non living. The non living things present in the environment constitute the physical aspect. It is directly related to human health, population and environment. This aspect includes natural resources like air, water, soil etc. Manmade components like development works, constructions, etc. have physical existence. The physical aspect constitute the environment and affect the health status of human being. Polluted environment containing harmful components causes various communicable and non-communicable diseases. Diseases germs live in the dirty and polluted environment. If they got opportunity to enter into the human body, they reproduce in our body significantly and become able to cause diseases. Physical aspects also include food materials, construction works, natural structures and abiotic components on the earth. 

2. Biological aspect 

Biological aspect includes the living components around us. Human beings themselves are biological components of the environment. They survive in the ecosystem with their predefined roles and positions. They make certain relationships with other living components of the environment. The domestic animals like buffalo, yak, pig, duck, etc. are raised for obtaining foods from them. Human population size directly or indirectly affects other domestic and wild animals in the environment. Flora and fauna, including micro-organisms, are also the components of the biological aspect. Domestic and wild animals, herbs, crops, trees, birds, reptiles and all components which are biotic members of existing ecosystem are the components of the biological aspect. Biological components are different in the Mountain, Hilly and Terai regions. They are indispensable aspects of human life. Fertility of soil and vividness of biotic components make human residence more convenient for survival. Biodiversity is one of the essential requisites of appropriate residential place for human beings on the earth. 

3. Economic aspect 

Economic aspect includes income, expenditure, employment, entrepreneurship, financial plans, budget and the factors related to the economic activities. It is essential for the fulfillment of human needs. People are engaged in various forms of income-generating activities like teaching, lawyering, farming, business, marketing, production of goods etc. These are also the components of the economic aspect. 

4. Socio-cultural aspect 

Socio-cultural aspect includes social norms, values, social systems, traditions and practices. Such factors are developed by people themselves for convenient livelihood and social cooperation. A human is a social animal because he/she lives in society with common life practices. 

5. Psychological aspect 

Psychological aspect is the key determinant of human behavior. It is related to the mental state of a human being. A positive attitude and behavior help in maintaining harmonious relationship among people. People who grow up in uncivilized family and poor culture usually have a negative attitude. 

It is always harmful for them. The psychological state cannot be described and understood just as an abstract aspect, rather it is determined by the mental health and healthy mental activities. 

6. Political aspect 

Political aspect determines the guidelines for almost all sectors of a nation. The government plays the central and key role in the formulation and implementation of national plans and policies. A government is made by political activities like election, activities of the political parties and other political movements. In this way, the political aspect of a nation determines the state of health, population and environment. 

7. Science and technological aspect 

This is the age of information and technology. Besides, people's new scientific achievements in the communication sector have brought miraculous changes in human life. The science and technological aspect includes scientific inventions, development of transportation vehicles and spaceships, new medical technologies like organ transplantation, genetic engineering, etc. It can save people's life at difficulties and protect the environment with its natural balance. Advancement of communication and information technologies with email and internet has become an eminent boom that can be used in health, population and environment fields for their promotion, conservation, education and public awareness related to them.
