IB DP ESS — Topic 1: Foundations | SL & HL | Paper 1 & Paper 2
🎯 Learning Intentions By the end of this note, you will be able to:
- Define the terms worldview, ecocentrism, technocentrism, and anthropocentrism using IB-aligned ESS terminology.
- Explain how different worldviews influence the way individuals, communities, and governments respond to environmental issues.
- Describe the spectrum of environmental value systems, from deep ecology to cornucopian technocentrism, and identify where different stakeholders sit on this spectrum.
- Distinguish between intrinsic and instrumental value in the context of environmental decision-making.
- Analyse how contrasting perspectives shape environmental policy and management outcomes at local, national, and global scales.
- Evaluate the strengths and limitations of different value systems when applied to real-world environmental problems such as climate change, biodiversity loss, and resource management.
- Discuss how indigenous and non-Western worldviews challenge dominant technocentric and anthropocentric frameworks in environmental decision-making.
Real-World Context & Relevance
In 2016, the Standing Rock Sioux Tribe in North Dakota, USA, mounted one of the most visible environmental protests in recent history against the Dakota Access Pipeline — a 1,886 km oil pipeline planned to cross beneath the Missouri River, the tribe's primary water source and a site of deep cultural and spiritual significance. The tribe's opposition was not primarily about carbon emissions or economic cost-benefit analysis. It was rooted in a fundamentally different relationship with the land: one in which rivers, soil, and living systems are not resources to be managed, but relatives to be respected. Meanwhile, the pipeline's developers and many state officials framed the project in terms of energy security, jobs, and economic growth. Two groups, looking at the same stretch of river, saw entirely different things — and that difference was not a matter of facts, but of values.
This tension is not unique to Standing Rock. It appears in every major environmental debate: whether to log old-growth forests in British Columbia, whether to mine rare earth minerals beneath the Atacama Desert, whether to build a wind farm on a Scottish peat bog. In each case, the scientific data alone cannot resolve the conflict. What determines the outcome is which values are given priority — and whose values are heard. Understanding why people hold different environmental perspectives, and how those perspectives shape decisions, is therefore not a philosophical luxury. It is one of the most practical skills an environmental scientist can develop.
🌍 Why This Matters Environmental problems are never purely technical. Every policy decision about land use, resource extraction, conservation, or climate action reflects a set of underlying values about what nature is worth, who it belongs to, and what obligations humans have toward it. Without understanding these value systems, environmental scientists risk proposing solutions that are technically sound but politically and culturally unworkable.
Core Concepts & Definitions
Before we can evaluate different environmental perspectives, we need a framework for understanding what shapes them. Every person who engages with an environmental issue — whether a farmer, a politician, a scientist, or an activist — brings with them a set of assumptions about the relationship between humans and the natural world. These assumptions are not random. They are organised into coherent systems of belief that philosophers and environmental scientists call worldviews or value systems. A worldview determines what a person thinks nature is for, what counts as an environmental problem, and what kinds of solutions are acceptable.
📖 Key Definition — Worldview (Environmental Value System) An environmental value system (or worldview) is a coherent set of
