Study Notes
Definition and Importance of Environment
- Environmental Science is a multi-disciplinary field combining studies in chemistry, physics, medical science, life sciences, agriculture, public health, and sanitary engineering.
- Studies interactions in air, water, and soil related to human activities and their effects on biological and physical species.
Literary Meaning of Environment
- Refers to external conditions influencing growth and development of living organisms and their working/living conditions.
- Key questions: What surrounds? By what? Where is it surrounded?
- Focuses on physical components like land, air, and water in supporting life in the biosphere.
Definitions of Environment
- Boring: Environment encompasses all stimuli from conception to death.
- Douglas and Holland: Environment consists of all external forces and conditions influencing life, behavior, growth, development, and maturity of organisms.
Scope of Environment
- Atmosphere: Protective gaseous layer surrounding the Earth.
- Hydrosphere: All water resources, including oceans, seas, lakes, rivers, streams, glaciers, and groundwater.
- Lithosphere: Solid Earth's outer mantle, including minerals in the crust and soil.
- Biosphere: Realm of living organisms and interactions with atmospheric, hydrospheric, and lithospheric elements.
Elements of Environment
- Physical Elements: Include space, landforms, water bodies, climate, soils, rocks, and minerals.
- Biological Elements: Comprise plants, animals, microorganisms, and humans, forming the biosphere.
- Cultural Elements: Man-made components like economic, social, and political aspects that shape cultural environments.
Types of Environments (According to Kurt Lewin)
-
Physical Environment: Influences geographical and climatic conditions affecting individuals.
- Example: Color of skin affected by climate (lighter in cold regions, darker in hot regions).
- Physique and working efficiency are also climate-dependent.
- Social and Cultural Environment: Encompasses social, economic, and political conditions affecting individuals.
- Psychological Environment: The mental and emotional context influencing personality formation.
Influences of Physical Environment
- Climate impacts human appearance and adaptation (e.g., skin color based on geographic location).
- Physical conditions can determine productivity and working efficiency.
