Population increase =
increase in energy
consumption - will
cause much greater

destruction
Threats to wildlife inc. 1)
habitat destruction 2) habitat
disturbance 3) overeploitation

Valuing Biodiversity in
terms of Ecosystem
Services
Direct
Use
Value:
economic
values
Indirect Use Value:
economic value of
natural services e.g.
climate regulation
Option Value: economic
values of future services that
a natural area could provide
Existance Value:
amount people would
be willing to pay to
avoid its destruction
