HUMAN RESOURCE USE
• ecological (carbon) footprint: how much we impact the environment
• sustainability: the ability to meet human needs
IMPORTANCE OF BIODIVERSITY
What happens if you remove a species?• Can lose biodiversity• Unbalance a food web• Areas already with low richness are most at
risk
PROTECTING ECOSYSTEMS
• Biodiversity hotspots: regions with the highest diversity that are most in danger
FIELDS OF STUDY
• Conservation biology: identify, protect, and maintain natural areas at risk
• Restoration biology: rebuild the damaged ecosystems
• Use bioindicators (species especially sensitive to change) as early warning signals of environmental problems
CASE STUDY:Saving the whooping crane
GOVERNMENT LAWS
• Debt-for-nature swap; richer countries or private companies pay smaller/poorer countries for undeveloped land or education programs
PRIVATE EFFORTS
• Ecotourism: tourism and conservation biology working together
MAINTENANCE OF BIODIVERSITY
• utilitarian value: economic values of biodiversity
• nonutilitarian value: life-forms have value
