Which of the following illustrates natural capital degradation?

Question

BlackTom AI · Accepted Answer

The question asks which option illustrates natural capital degradation. 
Option 1: 'use of wind power' — This is a form of renewable energy that generally reduces pressure on natural capital by producing energy without depleting water or fossil fuel resources. It does not illustrate degradation of natural capital. 
Option 2: 'saving endangered species' — This activity is protective of biodiversity, aiming to maintain or restore natural capital rather than degrade it. It reflects conservation rather than degradation. 
Option 3: 'aquifer depletion' — When groundwater is extracted faster than it is replenished, the aquifer loses its stored natural capital. Over time, this reduces the landscape’s long-term productivity and resilience, which is a classic example of natural capital degradation. 
Option 4: 'water runoff' — Runoff itself can lead to erosion, nutrient loss, and downstream pollution, which are environmental issues, but the phrase does not by itself denote degradation of natural capital; it describes a process that can contribute to degradation under certain conditions, yet it’s not as direct a illustration as aquifer depletion. 
Option 5: 'cleaning up pollution' — Cleanup is an restoration or remediation activity, aimed at reversing damage to natural capital rather than degrading it. It indicates recovery rather than degradation. 
In evaluating these, consider whether the scenario reduces the stock or quality of natural capital (the natural resources and ecosystem services a system relies on) over time. The option that most directly represents a net loss or depletion of that stock is aquifer depletion, whereas the others describe actions that either do not degrade natural capital or are actions aimed at protection or restoration rather than degradation.
