Multidisciplinary nature of Environmental studies

Hello, dear students. Today we are going to see the first chapter of unit one. That is multidisciplinary nature of environmental studies.

So, what is environment? Environment is derived from the French word environner, which means to encircle or surround. It is a sum total of all the external materials. That is living and non-living, events, and forces of nature which influence an organism. It is everything which affects the individual except the genes. Why we need to study environmental

studies? First of all is to deal with the environmental problems. What are the environmental problems? Then what are the problems cropped in the wake of development? Then we need an alternative solution to this problem. So, for that we require the environmental studies. It helps us to strain the fast depleting uh to conserve fast depleting natural

resources. It also help in wise planning of the development. And it creates a civil sense and create a sense of awareness among the individuals. Now, components of environment. There are four components of environment. Abiotic, biotic, social, and cultural. Physical or abiotic component can be divided into three types. Climatic factors. That is light, temperature,

rainfall. Humidity, atmosphere. Then topographic factors. That is height from sea level, direction from mountains and valleys, slope of hills, etc. And third is the edaphic or soil factors, that is fertility, color, quality, organic matter. Then comes the biotic component, which includes plants, animals, and microorganisms. Then comes the social components, which is related to the society, that is

population, social system, social changes, urbanization, industrialization, etc. Cultural component include all the moral values of life, religion, etc. So, these are the components of environment. Now, we'll see the segments of environment. Four segments are there, atmosphere, hydrosphere, lithosphere, and biosphere. We'll see one by one. Atmosphere is what? Atmosphere is the protective blanket of the gases
