CHAPTER 1: DEFINITION,SCOPE, AND IMPORTANCE LESSON 1: ENVIRONMENT D. Tulop, J. Serrano, R. LESSON 1 : ENVIRONMENT ENVIRONMENT AL SCIENCE ENVIRONMENT AL The Science of Environment studies is a SCIENCE multi-disciplinary science because it comprises various branches of studies like chemistry, physics, medical science, life science, agriculture, public health, sanitary engineering etc.  ENVIRONMENT AL SCIENCE It is the science of physical phenomena in the environment. It studies of the sources, reactions, transport, effect and fate of physical a biological species in the air, water and soil and the effect of from human activity. NVIRONMENT EXPLAINED Literary environment means the surrounding external conditions influencing development or growth of people, animal or plants; living or working conditions etc. This involves three questions: 1. What is Surrounded? 2. By what Surrounded? 3. Where Surrounded The answer to this question. It is in nature that physical component of the plant earth, viz land, air, water etc., support and affect life in the biosphere.  A. DEFINITION OF ENVIRONMENT 1. Boring: ‘A person’s environment consists of the sum total of the stimulation which he receives from his conception until his death.’ 2. Douglas and Holland: ‘The term environment is used to describe, in the aggregate, all the external forces, influences and conditions, which affect the life, nature, behaviour and the growth, development and maturity of living organisms.’ B. SCOPE OF ENVIRONMENT 1. ATMOSPHERE The atmosphere implies the protective blanket of gases, surrounding the earth. B. SCOPE OF ENVIRONMENT 2. HYDROSPHERE The Hydrosphere comprises all types of water resources oceans, seas, lakes, rivers, streams, reserviour, polar icecaps, glaciers, and ground water. B. SCOPE OF ENVIRONMENT 3. LITHOSPHERE Lithosphere is the outer mantle of the solid earth. It consists of minerals occurring in the earth’s crusts and the soil e.g. minerals, organic matter, air and water. B. SCOPE OF ENVIRONMENT 4. BIOSPHERE Biosphere indicates the realm of living organisms and their interactions with environment, viz atmosphere, hydrosphere and lithosphere. c. elements OF ENVIRONMENTS Environment is constituted by the interacting systems of physical, biological and cultural elements inter-related in various ways, individually as well as collectively. These elements may be explained as under: 1 Physical elements Physical elements are as space, landforms, water bodies, climate soils, rocks and minerals c. elements OF ENVIRONMENTS 2 Biological elements Biological elements such as plants, animals, microorganisms and men constitute the biosphere. c. elements OF ENVIRONMENTS 3 Cultural elements Cultural elements such as economic, social and political elements are essentially man made features, which make cultural milieu.  d. VARIOUS TYPES OF According ENVIRONMENTS to Kurt Lewin, environment is of three types which influence the personality of an individual as under 2 1 (b) Social and Cultural (a) Physical Environment, and Environment 3 (c) Psychological Environment 1 PHYSICAL ENVIRONMENT Physical environment, refers to geographical climate and weather or physical conditions wherein and individual lives. The human races are greatly influenced by the climate. 1 PHYSICAL ENVIRONMENT Some examples are as under: (a) In the cold countries i.e. European countries the people are of white colour. Likewise, in Asian and African countries, that is, in hot countries people are of dark complexion. (b) The physique of an individual depends on climate conditions as the individual tries to adjust in his physical environment. (c) The human working efficiency also depends on the climatic conditions. 2 SOCIAL ENVIRONMENT Social Environment includes an individual’s social, economic and political condition wherein he lives. The moral, cultural and emotional forces influence the life and nature of individual behaviour. 2 SOCIAL ENVIRONMENT Society may be classified into two categories as under: (i) An open society is very conductive for the individual development. (ii) A closed society is not very conductive for the developnment. 3 PSYCHOLOGICAL ENVIRONMENT Kurt Lewin has used the term ‘life space’ for explaining psychological environment. The Psychological environment enables us to understand the personality of an individual. Both the person and his goal form psychological environment.  "The environment and the economy are really both two sides of the same coin. If we cannot sustain the environment, we cannot sustain ourselves" - Wangari Maathai. Thank You!
