Yes. A resource may be renewable, but its extraction is unsustainable if the rate of use exceeds its rate of natural regeneration or if extraction, processing, and transport cause unacceptable environmental, social, or economic damage.
This is HL-only content from IB ESS subtopic 7.1 Natural resources: uses and management.
Why Renewable Does Not Automatically Mean Sustainable
A renewable resource can be replenished naturally on a human timescale. Sustainability, however, measures whether resource use maintains the long-term viability of the whole socio-ecological system without diminishing conditions for future generations.
Extraction becomes unsustainable through several mechanisms:
| Mechanism | Why it is unsustainable |
|---|---|
| Harvest exceeds regeneration | The resource stock declines because removal is faster than replacement. Overfishing can therefore collapse a renewable fish population. |
| Extraction damages ecosystems | Logging may remove renewable timber while causing soil erosion, habitat fragmentation, and biodiversity loss. |
| Processing uses finite resources | Processing timber or crops may consume fossil fuels, produce greenhouse gases, or require unsustainable water use. |
| Transport creates pollution | Moving renewable resources over long distances may increase carbon emissions and air pollution. |
| Benefits and harms are inequitable | Extraction may generate profits for companies while local or Indigenous communities experience displacement, pollution, or reduced access to natural resources. |
The collapse of the Grand Banks cod fishery in Canada illustrates the first mechanism. Cod populations were renewable, but industrial fishing removed fish faster than populations could reproduce. The resulting collapse damaged the ecosystem and caused severe unemployment in fishing communities.
The common misconception is that renewable means sustainable. Renewable describes the resource's capacity for replenishment; sustainable describes how the resource and the wider system are managed.
Exam Technique
For an explain question, link the extraction method to a clear consequence: identify the renewable resource, show how extraction exceeds regeneration or creates wider impacts, and explain why long-term availability is reduced. A named example such as the Grand Banks strengthens the application and shows both environmental and societal consequences.
