ENVIRONMENTAL STUDIES Unit-I : A Simple language notes for BAJMC Students (CCS University)

ENVIRONMENTAL STUDIES

UNIT–I: ENVIRONMENTAL STUDIES AND NATURAL RESOURCES

1. Environmental Studies: Meaning, Definition and Concept

Environmental Studies is an interdisciplinary area of study concerned with the relationship between human beings and their surroundings. It examines the physical, biological, social and cultural factors that influence life and the ways in which human activities affect the natural environment.

The word environment refers to the total surroundings in which organisms live and interact. It includes both living and non-living components. Air, water, soil, sunlight, temperature, plants, animals, microorganisms and human beings are all parts of the environment.

Environmental Studies therefore does not deal only with forests, animals or pollution. It covers a much wider field involving natural resources, ecosystems, biodiversity, pollution, conservation, sustainable development, human health, population and environmental awareness.

Simple Definition

Environment is the sum total of all living and non-living conditions surrounding an organism and influencing its life.

Environmental Studies helps us understand:

• How humans depend upon nature.
• How natural resources are used.
• How ecosystems function.
• How human activities create environmental problems.
• How environmental resources can be conserved.
• How development can be made sustainable.

 

2. Components of Environment

The environment can broadly be divided into two major components:

A. Biotic Components

Biotic means living.

These include:

• Human beings
• Plants
• Animals
• Birds
• Insects
• Bacteria
• Fungi
• Other microorganisms

All living organisms interact with each other and with non-living components.

Example

In a forest:

Trees → provide food and shelter → animals → microorganisms decompose dead matter → nutrients return to soil → plants use nutrients.

Thus, living components are interconnected.

 

B. Abiotic Components

Abiotic means non-living.

Important abiotic components include:

• Air
• Water
• Soil
• Sunlight
• Temperature
• Humidity
• Minerals
• Climate

Abiotic factors determine the conditions under which organisms survive.

Example

A plant requires:

Sunlight + Water + Carbon dioxide + Soil nutrients → Growth

Therefore, the survival of living organisms depends upon both biotic and abiotic components.

 

3. Scope of Environmental Studies

Environmental Studies has a very broad scope because environmental issues are connected with almost every area of human life.

Major areas of Environmental Studies

1. Natural resources
2. Ecosystems
3. Biodiversity
4. Environmental pollution
5. Environmental conservation
6. Sustainable development
7. Climate change
8. Waste management
9. Disaster management
10. Environmental health
11. Population and environment
12. Environmental ethics
13. Environmental legislation
14. Public awareness
15. Human activities and their environmental consequences

Environmental Studies is therefore interdisciplinary. It draws knowledge from:

• Biology
• Chemistry
• Geography
• Economics
• Sociology
• Political science
• Public health
• Journalism and Mass Communication

For BAJMC students, Environmental Studies is particularly relevant because environmental issues need to be communicated effectively to the public.

 

4. Importance of Environmental Studies

Environmental Studies is important because human survival and development depend directly on environmental resources.

4.1 Understanding Environmental Problems

It helps students understand problems such as:

• Pollution
• Deforestation
• Water scarcity
• Soil degradation
• Biodiversity loss
• Waste generation
• Climate change

Understanding a problem is the first step toward finding appropriate solutions.

4.2 Conservation of Natural Resources

Resources such as water, forests, minerals, land and energy are essential for human life and economic development.

Environmental Studies teaches responsible and efficient use of these resources.

4.3 Protection of Biodiversity

Plants, animals and microorganisms are important components of ecosystems. Environmental Studies creates awareness about the importance of biodiversity and the need for its conservation.

4.4 Sustainable Development

Development should improve human well-being without unnecessarily damaging the environment.

Environmental Studies introduces students to the concept of sustainable development, which seeks a balance between environmental protection, economic development and social well-being.

4.5 Environmental Health

Human health is closely related to environmental conditions.

For example:

Polluted air → respiratory problems

Contaminated water → water-borne diseases

Poor sanitation → health risks

Thus, environmental protection is also important for public health.

4.6 Development of Environmental Awareness

Environmental Studies encourages responsible behaviour such as:

• Saving water
• Saving electricity
• Reducing waste
• Recycling
• Planting trees
• Protecting wildlife

 

5. Need for Public Awareness

Environmental protection cannot be achieved only through government agencies. Individual citizens, educational institutions, industries, media organisations and communities all have important roles.

Why is public awareness necessary?

Many environmental problems are directly related to human behaviour.

For example:

• Throwing waste in public places
• Excessive use of plastic
• Wasting water
• Unnecessary electricity consumption
• Illegal cutting of trees
• Excessive use of private vehicles

If people understand the consequences of these activities, they can adopt more responsible practices.

Methods of Environmental Awareness

Environmental awareness can be created through:

• Schools and universities
• Newspapers
• Television
• Radio
• Social media
• Documentaries
• Public campaigns
• Advertisements
• Seminars and workshops
• Community programmes
• Environmental journalism

 

6. Role of Media in Environmental Awareness

For students of Journalism and Mass Communication, this is an important application of Unit I.

Media can help society understand environmental problems by:

6.1 Environmental Reporting

Journalists can report:

• Water pollution
• Deforestation
• Waste-management problems
• Air pollution
• Wildlife issues
• Water scarcity
• Environmental disasters

6.2 Public Awareness Campaigns

Television, radio, newspapers and digital media can promote:

• Water conservation
• Tree plantation
• Waste segregation
• Recycling
• Energy conservation

6.3 Environmental Documentary

Documentaries can visually explain environmental problems and their effects.

6.4 Social Media

Social media provides opportunities for:

• Environmental campaigns
• Infographics
• Short videos
• Public discussions
• Community mobilisation

6.5 Environmental Advertisements

Advertisements can encourage responsible behaviour.

For example:

“Save Water”

“Reduce, Reuse, Recycle”

“Plant Trees”

Thus, journalism and mass communication can become important tools for environmental awareness.

 

7. Natural Resources

Natural resources are materials, substances and forms of energy obtained from nature and used by human beings.

Examples include:

• Forests
• Water
• Minerals
• Land
• Food
• Solar energy
• Wind
• Coal
• Petroleum
• Natural gas

Natural resources support human survival, economic activity and social development.

 

8. Types of Natural Resources

Natural resources can be classified in several ways.

Renewable Resources

Renewable resources can naturally replenish over time when they are used responsibly.

Examples:

• Solar energy
• Wind energy
• Water

• Use public transport where practical.
• Share rides where possible.

 

16. Equitable Use of Resources for Sustainable Lifestyles

Natural resources are not unlimited. Therefore, their use should be equitable and responsible.

Equitable use means ensuring fair access to resources while avoiding unnecessary exploitation.

A sustainable lifestyle seeks to reduce environmental pressure while meeting human needs.

Examples

Instead of:

Excessive water use → Responsible water use

Throwing away usable items → Reuse

Unnecessary electricity consumption → Energy conservation

Excessive private vehicle use → Public transport where practical

The objective is not to stop development but to make development environmentally responsible.

 

17. Sustainable Lifestyle

A sustainable lifestyle involves making choices that reduce unnecessary pressure on the environment.

Five simple principles

R – Reduce
Reduce unnecessary consumption.

R – Reuse
Use products repeatedly where possible.

R – Recycle
Send suitable materials for recycling.

R – Repair
Repair usable products rather than immediately discarding them.

R – Respect Nature
Protect natural resources and biodiversity.

 

18. Environmental Conservation and Journalism

For a BAJMC student, environmental conservation also has a communication dimension.

A journalist can:

1. Investigate environmental issues.
2. Report environmental problems accurately.
3. Present scientific information in understandable language.
4. Highlight community-level environmental concerns.
5. Give visibility to conservation initiatives.
6. Create public awareness.
7. Encourage responsible environmental behaviour.

Example

If a city faces water scarcity, a journalist can prepare a report covering:

Problem → Causes → Impact on people → Expert views → Government measures → Community solutions → Public action

This converts environmental information into meaningful public communication.
