Land Use

Introduction: Human Land Use

• Humans reduce land available for animals and plants.

• Land is used for:

  • Buildings: houses, factories, shops, airports.

  • Farms and quarries.

  • Waste disposal: e.g., landfills.

• Result: habitat loss → reduced biodiversity.

Peat Bogs

• Peat bogs/peatlands contain large amounts of dead plant material.

• Decay is slow due to waterlogged conditions → peat stores trapped carbon.

• Human use of peat:

  • Compost production for gardens and farms.

  • Burning for energy (e.g., electricity generation).

• Effects of peat destruction:

  • Reduces the area of habitat → fewer species of animals, plants, and microorganisms → loss of biodiversity.

  • When peat decays or is burned → releases CO₂ → contributes to climate change.

Challenges & Considerations

• Gardeners and farmers moving away from peat-based compost to protect biodiversity.

• Alternatives are more expensive → could increase food prices if widely adopted.

• No simple solution: balancing biodiversity protection vs. human needs.

✅ Summary / Key Points

• Human land use reduces available habitats, lowering biodiversity.

• Peat bog destruction:

  • Reduces habitat.

  • Releases carbon dioxide, contributing to climate change.

• Managing peat and land use requires balancing environmental protection and human requirements.
