- Can be renewable or non-renewable
- Essential for human survival and development
- Provide food, water, energy, materials, and shelter
Types of natural resources:
1. Renewable resources (can be replenished):
a) Forests - provide timber, paper, fruits, medicines
- Regenerate through growth
- Can become depleted if exploited unsustainably
b) Water - fresh water for drinking and agriculture
- Regenerates throug...
Q2: Explain the management and conservation of forests and wildlife.
Forest management and conservation:
Forests:
- Cover about 31% of world's land area

- Provide timber, paper, medicines, food
- Habitat for wildlife
- Prevent soil erosion
- Regulate water cycle
Problems with forests:
1. Deforestation - clearing of forests for agriculture, timber, urbanization
2. Overexploitation - cutting more trees than grow back
3. Forest fires - destroy large areas
4. Pests and diseases
5. Habitat fragmentation

- Buried under sedimentary rocks
- High pressure and temperature transformed plant matter
- Carbon-rich remains became coal
- Coal is fossilized plant material
Properties of coal:
- Black or brown mineral
- Hardness varies by type (lignite < bituminous < anthracite)
- Non-renewable resource
- Limited reserves (may last 1...
