The Value of Biodiversity

3. Periwinkle Example of a plant increasing the survival rate of childhood leukemia.
4. Medicines derived from chemical structures identified in natural products.
7. Ecosystems acting as water purifying systems.
8. Variability among living organisms from all sources.
10. Biomass used for heating and cooking.
11. Ecosystems trapping silt, reducing impacts on marine ecosystems
13. Resources Protection of ecosystems against extremes of flood and drought.
16. Type of use value assigned to goods consumed locally.
17. Pertaining to variations between populations of species.
19. Ethical value based on respect for life and reverence for the living world.
20. Result of vegetation removal, reducing water yield and quality.
21. of Medicine Wild populations acting as blueprints for manufacturing medicines.
22. Direct and indirect benefit to humans derived from biodiversity.

1. Use Value assigned to goods neither bought nor sold, contributing to local consumption.
2. Extract from the bark of the Cinchona tree, used for malaria treatment.
5. The value of biodiversity associated with direct and indirect economic benefits to humans.
6. Example of a medicine cheaper to synthesize than to grow.
9. Type of use value assigned to goods bought and sold locally.
12. Removal Leads to siltation of reservoirs and deterioration of aquatic habitats.
14. Economic Value Economic benefits without direct consumption.
15. Result of increased demand for fuelwood, leading to environmental degradation.
16. Tree Source of quinine for malaria treatment.
18. Agreement defining biodiversity as variability among living organisms.
21. of Living Declines when environmental quality deteriorates.
