Applying Economic Models to Environmental Crises
Conceptual models originally developed to explain economic phenomena, including concepts like positive feedback, lock-in, tipping points, and equilibria, are now being used to provide a deeper understanding of environmental crises.

Analyzing Systemic Instability
Which of the following scenarios best illustrates the core characteristic of an unstable system, where internal dynamics push it further from equilibrium?
Match each description of a system's behavior with the term that best characterizes it.
An economic or environmental system is defined as unstable primarily when powerful external events, such as a major policy shift or a natural catastrophe, are strong enough to disrupt its equilibrium.
The Mechanism of Systemic Instability
A stable environmental system can be pushed into a state of instability where its own internal dynamics drive it further from its original equilibrium. Arrange the following events describing the melting of an arctic ice sheet into the correct logical sequence that illustrates this process of escalating instability.

Comparing Dynamics of Systemic Instability
A system is considered unstable when its internal processes react to a disturbance. Which of the following descriptions of a system's reaction to a small disturbance most accurately characterizes this state of instability?

Analyzing Ecosystem Collapse with Economic Concepts
An environmental scientist observes that a coral reef ecosystem can withstand a certain level of ocean warming. However, once a critical temperature threshold is passed, a rapid, self-reinforcing process of coral bleaching begins, leading to a sudden and largely irreversible collapse of the entire ecosystem. Which economic concept best describes this phenomenon?
Analyzing Feedback Loops in Economic and Environmental Systems
Match each conceptual modeling term, often used in economics, to the environmental scenario it best describes.
The Fossil Fuel 'Lock-In' Effect
An environmental policy is implemented to gradually reduce pollution in a lake. For several years, the policy leads to slow but steady improvements in water quality. This indicates the lake system is dominated by a positive feedback loop, pushing it towards a healthy, stable state.
A conceptual model describes the relationship between an environmental stressor (e.g., pollution) and the state of an ecosystem (e.g., health). The model predicts two possible stable states: a 'healthy' state and a 'degraded' state.
- When the ecosystem is in the 'healthy' state, it can absorb the stressor up to a critical threshold, or 'tipping point'.
- If the stressor increases beyond this first tipping point, the system rapidly collapses into the 'degraded' stable state.
- To recover the 'healthy' state, the stressor must be reduced to a level significantly lower than the first tipping point, crossing a second, lower tipping point.
Given this model, if a healthy ecosystem experiences a gradual increase in the stressor that pushes it just past the first tipping point, what is the most likely consequence?

A semi-arid grassland ecosystem, which has been stable for centuries, undergoes a rapid and irreversible transformation into a desert. Arrange the following events to show the most likely causal sequence that describes this system's collapse.
