  1. ENVIRONMENTAL SOLUTIONS pp 444 - 452

  2. Threat to Biodiversity video

  3. HUMAN RESOURCE USE • ecological (carbon) footprint: amount of land and sea required to supply the resources to fit your lifestyle needs

  4. HUMAN RESOURCE USE • ecological (carbon) footprint: amount of land and sea required to supply the resources to fit your lifestyle needs •  how much we impact the environment In 2007 humanity’s total ecological footprint was ~1.5 earth’s

  5. HUMAN RESOURCE USE • sustainability: the ability to meet human needs so the human population can survive indefinitely

  6. FIELDS OF STUDY • Conservation biology: identify, protect, and maintain natural areas at risk

  7. FIELDS OF STUDY • Conservation biology: identify, protect, and maintain natural areas at risk • Restoration biology: rebuild the damaged ecosystems

  8. 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

  9. CASE STUDY:Saving the whooping crane Whooping crane: in 1870 about 20 K migrated between the US and Canada, but 1937, only 15 American settlers began to hunt the birds for feathers By 1967 the US Fish and Wildlife Service began a captive breeding program which now produces about 30 cranes/year

  10. PROTECTING ECOSYSTEMS • Biodiversity hotspots: regions with the highest diversity that are most in danger

  11. GOVERNMENT LAWS • Debt-for-nature swap: portion of a developing nation foreign debt is forgiven in exchange for investment in environmental conservation.

  12. PRIVATE EFFORTS • Ecotourism: tourism and conservation biology working together • Visiting fragile nature with low impact • Educates traveler, provides funds for conservation, and may increase economics of country

  13. PRIVATE EFFORTS • Ecotourism: tourism and conservation biology working together • Visiting fragile nature with low impact • Educates traveler, provides funds for conservation, and may increase economics of country
