Multidisciplinary Nature of Environmental Studies
Overview
Every course you take studies one slice of the world. Environmental studies is different: it asks how the whole system of air, water, land, living things and human societies fits together, and what happens when we disturb it. This short opening module defines the field, shows why it needs many disciplines, and explains why public awareness matters.
Learning objectives
By the end of this module, you’ll be able to:
- 1Define the environment and environmental studies, and describe the scope of the subject
- 2Explain why environmental problems cannot be solved by one discipline alone
- 3Argue why public awareness and individual action matter, with examples
1.1 Definition, Scope and Importance

What is the “environment”?
The environment is everything that surrounds a living being and influences it: the physical surroundings (air, water, soil, climate), the living world (plants, animals, microbes) and the human-made and social setting (cities, institutions, culture). These parts constantly interact.
The four classic components
- Atmosphere — the layer of gases around the Earth
- Hydrosphere — all water: oceans, rivers, lakes, ice, groundwater
- Lithosphere — rocks, minerals and soil
- Biosphere — the zone where life exists, which overlaps the other three
Why it is multidisciplinary
A single environmental problem usually has scientific, economic, social, legal and ethical sides at once. Take a polluted river: chemistry explains what is in the water, ecology shows what it does to fish, economics asks who pays for treatment, law decides who is liable, and sociology asks whose livelihoods are affected.
| Discipline | What it contributes |
|---|---|
| Biology, ecology | How organisms and ecosystems function |
| Chemistry, physics | Pollutants, energy, climate processes |
| Geology, geography | Resources, landforms, hazards, mapping |
| Economics | Costs, incentives, resource pricing |
| Sociology, history, anthropology | Communities, livelihoods, traditional knowledge |
| Law, political science | Regulation, rights, governance |
| Ethics, media, education | Values, communication, behaviour change |
Scope
The scope of environmental studies runs from local to global and covers natural resources, ecosystems, biodiversity, pollution, waste, climate change, population, sustainable development and environmental law. It also opens careers beyond the sciences, for example environmental journalism, impact assessment, sustainability and CSR roles, wildlife and forest management, planning, and community advocacy.
Importance
- Life support: clean air, water, food and climate stability all come from natural systems
- Livelihoods: farming, fishing, forestry and tourism depend directly on environmental health
- Health: pollution and degraded ecosystems raise disease burdens
- Fairness: environmental harm usually falls hardest on poorer and marginalised communities
- The future: sustainable development means meeting present needs without ruining what later generations need
1.2 Need for Public Awareness
Three topics — click to expand each one.
Why awareness matters
Environmental problems are mostly the sum of millions of small decisions: what we buy, burn, throw away and vote for. Laws and technology help, but they work only when people understand the problem and support the solution. Awareness also lets citizens notice violations, ask questions of authorities and take part in decisions.
This is why, in 1991, the Supreme Court of India (in M.C. Mehta v. Union of India) directed that environmental education be introduced at every level of schooling and college. That direction is the origin of this very course.
How awareness is built
- Education: formal courses, eco-clubs, field visits
- Media and campaigns: documentaries, news, social media, days such as World Environment Day (5 June)
- Community action: local movements, citizen science, neighbourhood clean-ups
- Policy nudges: labelling, bans on single-use plastics, public data portals
Milestones in global environmental awareness
| Year | Event | Why it matters |
|---|---|---|
| 1972 | UN Conference on the Human Environment, Stockholm | First major global environment conference; led to UNEP and World Environment Day |
| 1984 | Bhopal gas disaster | Pushed India to enact the Environment (Protection) Act, 1986 |
| 1992 | Earth Summit, Rio de Janeiro | Sustainable development, climate and biodiversity conventions |
| 2002 | World Summit on Sustainable Development, Johannesburg | Reviewed progress since Rio |
| 2015 | Paris Agreement and the SDGs | Global climate goal and a 2030 development agenda |
