🧠 Memory Aid
Human causes of biodiversity loss — "WILD" mnemonic:
- Waste and pollution (water, land, air)
- Intensive land use (farming, building, quarrying)
- Loss of forests (deforestation)
- Destruction of peat bogs
Conservation methods — "BRP + SHR" (Breeding, Replanting, Protected areas + Seed banks, Hedgerows, Recycling):
- Breeding programmes for endangered species
- Reforestation — planting trees to restore habitats
- Protected areas — SSSIs, national parks, nature reserves
- Seed banks — frozen insurance for plant diversity
- Hedgerow and field margin restoration
- Recycling — reduces waste going to landfill
The peat bog cycle: "PEAT protects — Preserve it!" Peat bogs Preserve organic carbon by keeping it Enclosed in Anaerobic, waterlogged conditions and locked away for Thousands of years. Drain them and that carbon escapes as CO₂.
