Topic Synopsis
This topic introduces the concept of natural resources, defining them as environmental features used to meet human needs. It covers the classification of resources, the methods of exploitation, and the resulting environmental impacts.
Key Concepts & Core Principles
- Renewable vs non-renewable resources: Renewable resources (e.g., wind, solar) can be replenished naturally over short timescales, while non-renewable resources (e.g., oil, coal) exist in finite quantities and will eventually run out.
- Resource distribution: Natural resources are unevenly distributed due to geological and climatic factors. For example, fossil fuels are found in sedimentary basins, while sunlight is more abundant in equatorial regions.
- Resource security: This refers to the reliable availability of a resource at an affordable price. Countries with high resource security can meet their needs, while those with low security face shortages and conflict.
- Sustainable management: Using resources in a way that meets current needs without compromising the ability of future generations to meet theirs. Examples include reducing waste, using renewable energy, and implementing recycling schemes.
- Environmental impact: Extraction and use of natural resources can cause pollution, habitat destruction, and climate change. Understanding these impacts is key to evaluating management strategies.
Exam Tips & Revision Strategies
- Ensure you can clearly define and provide examples for biotic, abiotic, renewable, and non-renewable resources.
- Be prepared to explain the causal link between human exploitation activities and environmental degradation.
- Use specific terminology when describing environmental impacts (e.g., soil erosion, biodiversity loss).
Common Misconceptions & Mistakes to Avoid
- Confusing the definition of natural resources with specific examples.
- Failing to link the method of exploitation directly to the specific environmental impact.
- Overlooking the distinction between biotic and abiotic resources.
Examiner Marking Points
- Definition and classification of natural resources as biotic, abiotic, renewable, and non-renewable.
- Methods of resource exploitation including extraction of fossil fuels, fishing, farming, and deforestation.
- Environmental impacts of resource exploitation such as reduced biodiversity, soil erosion, and degradation of water and air quality.
