Definition, scope and Importance of environment science

1. Definition, scope and Importance of environment science Prepared by , Mr. Snehal Patel Assistant Professor, Sumandeep Vidyapeeth, Vadodara, Gujarat, India.

2. Definition of Environmental Science The word environment is derived from French word “ environ” which means surrounding or enveloping. Environmental science is a multidisciplinary science which combines physics, chemistry, biology, medical, health science, life science, agricultural science, forestry, public health engineering and so on. The main objective of environmental science is to protect the environment.

3. Definition of Environment All the factors such as physical, geographical, chemical, biological, and ecological which affects human life and its existance on this planet are called environment. The environment includes earth, lakes, forests, farms, vegetation and other biological life such as animals, plants, bacteria and micro-organisms etc. All the components of the environment are basically divided into two categories. Biotic environment Abiotic environment

4. Biotic and Abiotic environment Biotic environment includes all living organisms and biological life such as animals, birds, forests, reptiles, insects, bacteria and micro-organisms like algae, fungus etc. Abiotic environment includes all non-living components such as land, mountains, rivers, air, water, temperature, humidity, water vapour, sand, dust, clouds etc.

5. Scope of Environmental Science Our surrounding includes forest, rivers, mountains, desert, or a combination of these elements. Most of us live in landscapes that have been heavily modified by the human beings in villages, towns and cities. But even those of us who live in cities get our food supply from surrounding villages. We use water to drink and other day to day activities, we breath air , we use resources from which food is made. Our dependence on nature is so great that we cannot continue to live without protecting the earths environmental resources.

6. Importance of Environment Environment is not a single subject. It is an integration of several subjects that includes both science and social science. To understand all the different aspects of our environment we need to understand biology, chemistry, physics, geography, resources management, economics and population issue. Thus the scope of environmental studies is extremely wide and covers some aspects of nearly every major discipline. We will in a world in which natural resources are limited. Water, air, soil, minerals, oils, the product we get from the forests, grasslands, oceans, and from agriculture and from livestock are all the part of our life support system. Without them life it self will be impossible.

7. Importance of Environment As we keep on increasing in number the quantity of resources each of us uses also increases. The earth cannot be expected to sustain this expanding level of utilization of resources. Added to this is misuse of resources . We waste or pollute large amount of natures clean water; we create more and more amount of plastic that we discard after the single use. We waste large amount of food, which is discarded as garbage. Air pollution leads to respiratory diseases. Water pollution leads to gastrointestinal (GIT) disorder. And many pollutants are known to cause cancer. Improving this situation will only happen if each of use begins to take actions in our daily lives that will help preserve our environmental resources. We cannot expect government alone to manage the safe guarding of our environment nor can we expect other people to prevent environmental damage. We need to do it ourselves.
