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 ecocentric, anthropocentric, and technocentric worldviews using IB-aligned ESS terminology.
- Explain how shifting cultural, scientific, and political perspectives have shaped the development of the modern environmental movement.
- Describe key milestones in the history of the environmental movement, including landmark publications, legislation, and international agreements.
- Analyse how different worldviews lead to contrasting approaches to environmental management, using the ESS analysis parameters of perspectives, sustainability, and trade-offs.
- Evaluate the effectiveness of the environmental movement in influencing policy and changing societal attitudes toward the natural world.
- Discuss the tensions between ecocentric, anthropocentric, and technocentric worldviews in the context of real environmental decisions and international agreements.
- Outline the role of non-governmental organisations (NGOs), scientific bodies, and individuals in driving environmental awareness and policy change.
Real-World Context & Relevance
In September 2019, an estimated four million people in 161 countries took to the streets in the largest climate strike in history, inspired in large part by a sixteen-year-old Swedish student named Greta Thunberg who had begun sitting outside the Swedish parliament just one year earlier. This extraordinary mobilisation did not emerge from nowhere. It was the latest expression of a movement that had been building for over a century — one rooted in a fundamental shift in how human societies perceive their relationship with the natural world. The question of whether nature exists to serve human needs, or whether it has intrinsic value independent of human use, sits at the heart of every major environmental debate.
Yet the environmental movement has not followed a single, linear path. In the United States, the conservation movement of the late nineteenth century was driven by figures like John Muir, who argued for the preservation of wilderness for its own sake, while Gifford Pinchot championed the "wise use" of natural resources for human benefit — a tension that persists in environmental policy today. Globally, the contrast is even sharper: while wealthy nations debated the aesthetics of national parks, communities in the Global South were experiencing the direct ecological consequences of colonial resource extraction. Understanding how these perspectives evolved — and how they continue to shape environmental governance — is foundational to ESS.
🌍 Why This Matters The worldview a society holds about its relationship with nature directly determines the environmental policies it adopts, the international agreements it signs, and the trade-offs it is willing to accept. Without understanding the historical and philosophical roots of environmental thinking, it is impossible to critically evaluate why some environmental problems are addressed effectively while others persist despite decades of scientific evidence.
Core Concepts & Definitions
Before examining the historical arc of the environmental movement, it is essential to understand the philosophical foundations that underpin different approaches to environmental management. When societies make decisions about forests, fisheries, or fossil fuels, those decisions are never purely technical — they reflect deeper assumptions about what nature is for, who has the right to use it, and what obligations humans have toward other species and future generations. These assumptions can be grouped into three broad worldview categories that recur throughout environmental history.
📖 Key Definition — Ecocentric Worldview An ecocentric worldview holds that all living organisms and ecosystems have intrinsic value — value that exists independently of their usefulness to humans. From this perspective,
