Environment:
Environment contains phenomenon, materials & features. It is a mixture of various elements and compounds. It is a physical & biological world where we survive. The components of environment are
1. physical surrounding
2. living organisms
3. Meteorological factors or climate factors
Environment is classified into
1. Physical or abiotic environment: It contains external physical factors like temperature, humidity, water, minerals and gases.
2. Living or biotic environment: It contains living creatures like plants, animals & microorganisms.
3. Natural environment: It contains physical & natural features like mountains, hills, valleys, basins, gases, trees, rocks & minerals,sand & soils etc.
4. Cultural environment: It contains Man made features like roads, railways, buildings bridges, dams etc.
Factors affecting environment:
- Topograhic or physiographic
Example: river, lake, sea level etc.
- Climate
Example: light , temperature etc
- Edaphic
Example: Lithosphere, soil etc
- Biotic:
Example: man. Animals, plants etc
Thus environment means what lies around us. Physical and biological world where we live. Mixture of various elements and components.
Environmental problems:
1. Pollution
2. Urbanization
3. Industrialization
4. Disasters
5. Deforestation
6. Global warming
7. Erosion of soil
Environmental Education: Place in curriculum & life:
1. Bring awareness & gives knowledge about environment
2. Develops skills & abilities to conserve environment
3. Participate in solving real environmental problems
4. Create positive attitude towards environment
5. To conserve environment
6. For sustainable life
7. Basic knowledge and understanding of environment
8. eco friendly dwelling
9. Judicious utilization of exiting resources
Definition & concept of environmental education:
- Environmental education is the education through environment, about environment and for the environment.
- Environment education is a process which recognizing the value and clarifies the concept. Develops skills and attitudes to understand & appreciate the inter relatedness of man his culture & his bio- physical surroundings.
- Environmental education entails practice decision making, self formulation of a code of a behaviour, about issues concerning environment quality.
- Environmental education is an activity with organized groups that are designed to develop understanding appreciating & caring for the natural environment.
Thus EE
- acquisition of a critical understanding of human ecological principles & processes
- Teach people about the natural world & particularly about ways in which ecosystem works
- Perception about value of natural world & how to change environmental behaviour
- Balanced growth & understanding of the environment
- Harmonious living with natural resources
Creating awareness about the environment: Importance
- Rapidly dwindling of natural resources
- Increasing degradation of environment by human activities
- Advancement in technology
- Explosive increase in human population
- scarcity of space & food
- Deterioration of hygienic condition
- Global warming
- urbanization (dirt, disease, disasters, sanitation, illhealth etc.) Industrialization (carbon dioxide, radio active nuclear wastes etc.)
- Deforestation
- pollution of natural resources
- Imbalance in ecological order, pressure on natural resources due to increase in population
- Agricultural growth (High yielding varieties, cause soil salinity, damage physical structure of soil)
- Rural life (Firewood, over grazing)
- Need of ground water (safe drinking water, clean water bodies)
Nature of environmental education:
1. Social nature:
One man can conserve entire environment. One person action is followed by other person. People follow each other. Social activities are carried out in society to conserve the environment based on culture of society.
2. Dynamic nature:
Environment which our forefathers have cherished, we do not have same. This means its keep on changing. Constant change in environment because of individual needs.
3. Scientific Nature:
It is based on research. Based on evidence.
4. Complex nature:
Intense relationship between environmental components – elements. Aspect of environment is linked with one another. Solving one problem give rise to another problem. Variety of physical, biological and human activities are carried out.
5. Global nature:
It is universal. Not keep on telling save environment but to do something for it. It is not enough to know environment.
6. Practical Nature:
It is based on skills development
