Your Environmental Compass
An Environmental Value System (EVS) is like your personal compass for navigating environmental issues. It's a worldview that guides your beliefs and actions, ranging from putting nature first to believing technology can solve all our problems.
Imagine you share a kitchen with several flatmates. An ecocentric person might insist on composting all food scraps and using only natural cleaning products because they believe the kitchen's 'ecosystem' has intrinsic value. An anthropocentric person would focus on creating a cleaning rota and rules for fair use of the fridge, ensuring the kitchen serves all humans well. A technocentric person might buy a new, ultra-efficient dishwasher and a self-cleaning oven, believing technology is the best way to manage the kitchen for everyone's benefit.

First, understand that an Environmental Value System (EVS) is a personal worldview shaping your relationship with the environment, influenced by your culture, education, and experiences.
- 2
Next, place the main EVSs on a spectrum: Ecocentrism (nature-centred), Anthropocentrism (human-centred), and Technocentrism (technology-centred), recognising there are variations within each.
- 3
Then, apply these different EVSs to analyse a specific environmental issue, such as deforestation, predicting the different solutions each EVS would propose.
- 4
Finally, connect these worldviews to the concept of sustainability, evaluating how each EVS interprets and prioritises the goal of meeting present needs without compromising the future.

Understanding Environmental Value Systems (EVS)
An Environmental Value System is a comprehensive worldview that shapes how we perceive and interact with our environment. It's not just a single opinion, but a complex system of inputs and outputs. Inputs include education, cultural background, religious beliefs, personal experiences, and media influence. These inputs mould our perspective, leading to outputs such as our decisions, actions, and chosen lifestyles. For example, your decision on whether to buy organic food, support a wind farm, or cycle to school is an output of your EVS.
The Spectrum of Environmental Philosophies
EVSs are best understood as a continuous spectrum rather than discrete categories. However, for analysis, we can group them into three main philosophies: ecocentrism, anthropocentrism, and technocentrism. It's important to remember that individuals and societies can exhibit traits from different parts of the spectrum, but often have a dominant leaning.
Ecocentrism (Nature-centred): This EVS places intrinsic value on nature. It stresses the importance of ecological limits and the need for humans to live within them. It has two main branches:
- Deep Ecologists: Believe nature has inherent rights (biorights). They advocate for a radical shift in human consciousness and a decrease in population and consumption.
- Self-Reliance (Soft) Ecologists: Favour small-scale, community-led action and appropriate technology. They believe in personal responsibility and a less materialistic society.
Anthropocentrism (Human-centred): This EVS places humans as the dominant species. Nature is valued for the resources and services it provides to humanity. It includes:
- Environmental Managers: Believe humans should manage the planet for sustainable use. They support policies, regulations, and economic tools (e.g., 'polluter pays' principle) to solve environmental problems.
Technocentrism (Technology-centred): This EVS is optimistic about the power of technology and human ingenuity to solve environmental problems. It includes:
- Cornucopians: An extreme view that believes resources are infinite or that substitutes can always be found. They see environmental problems as temporary challenges that technology will overcome.
In exam questions, especially those asking you to 'discuss' or 'compare', using the specific names of philosophies (e.g., 'A Cornucopian Technocentrist would argue...') demonstrates a higher level of understanding than just saying 'some people believe technology will solve it'. Be precise with your terminology.
Sustainability and the Millennium Ecosystem Assessment
Sustainability is a central concept in ESS. It refers to the ability to maintain ecological balance while meeting human needs. The most famous definition comes from the 1987 Brundtland Report: 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs.' This is known as sustainable development, the pathway to achieving the goal of sustainability. It is often represented by three interconnected pillars: environmental protection, social equity, and economic viability.
Sustainable Development = Environmental Protection + Social Equity + Economic Viability
The Millennium Ecosystem Assessment (MEA), published in 2005, was a landmark study that provided a scientific basis for the link between ecosystems and human well-being. It concluded that over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period in human history, largely to meet growing demands for food, fresh water, timber, fibre, and fuel. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth. The MEA categorised the benefits people obtain from ecosystems into four types of 'ecosystem services'.
MEA Ecosystem Services:
Provisioning Services: The products obtained from ecosystems (e.g., food, water, wood, fibre).
Regulating Services: The benefits obtained from the regulation of ecosystem processes (e.g., climate regulation, flood control, water purification).
Cultural Services: The non-material benefits people obtain from ecosystems (e.g., spiritual enrichment, recreation, aesthetic experiences).
Supporting Services: Services necessary for the production of all other ecosystem services (e.g., nutrient cycling, soil formation, primary production).
Worked examples

A new proposal suggests creating a large marine protected area (MPA) where all fishing is banned to allow fish stocks to recover. Compare and contrast the likely responses of a Deep Ecologist and a Cornucopian Technocentrist to this proposal. [4 marks]
- 1
A Deep Ecologist would strongly support the proposal. [1] They believe that the marine ecosystem and its fish have an intrinsic right to exist and flourish, independent of human needs (biorights). [1] They would see the ban as a necessary step to restore the natural balance that human activity has disrupted.
Evaluate the construction of a large-scale solar power farm in a desert ecosystem from the perspective of an Environmental Manager and a Self-Reliance Ecologist. [6 marks]
- 1
An Environmental Manager would likely support the project, with caveats. [1] They would see it as a pragmatic, human-managed solution to reduce reliance on fossil fuels, thus mitigating climate change. [1] They would advocate for a thorough Environmental Impact Assessment (EIA) to minimise harm to desert wildlife and would support legislation to ensure the benefits (clean energy) are distributed fairly, perhaps through a national grid. [1] The economic viability and contribution to national energy security would be key positive factors.

Environmental Value System (EVS)
A worldview or paradigm that shapes the way an individual or group of people perceives and evaluates environmental issues. It is influenced by cultural, religious, economic, and socio-political contexts.
