Presentation Transcript

  1. Biodiversity Components and Benefits

  2. One important renewable resource is biodiversity: The different life forms and life sustaining processes • Biodiversity has four main components • Species Diversity • Genetic Diversity • Ecological Diversity • Functional Diversity Biodiversity

  3. The number and abundance of species present in different communities Species Diversity

  4. The variety of genetic material within a species or population Genetic Diversity

  5. The variety of ecosystems found on an area or on earth Ecological Diversity

  6. The biological and chemical processes such as energy flow and matter recycling needed for the survival of living things. Functional Diversity

  7. Biodiversity provides us with: • Natural Resources (food water, wood, energy, and medicines) • Natural Services (air and water purification, soil fertility, waste disposal, pest control) • Aesthetic pleasure Why Should We Care About Biodiversity?

  8. Fossil Evidence, chemical analysis, Ice Core samples, and DNA analysis demonstrate that the biodiversity today is different from the biodiversity in the past Biodiversity of the Past Figure 4-4

  9. Ecosystem Services • Ecosystem Function • Food Security • Drugs and Medicine • Tourism and Recreation • Keeping in Touch With Nature Benefits of Biodiversity

  10. Service that nature provides humans/ecosystems • Clean air from plants Ecosystem Services

  11. Increased biodiversity means more stability and better chance at bouncing back • Keystone species: take it away, ecosystem fumbles Ecosystem Function

  12. Increased biodiversity (of crops) means more stable (disease resistant, tougher) • Is this better for the future? • Seed banks Food Security

  13. Lots of drugs come from plants and other organisms (mostly the rainforest) • Aspirin Drugs and Medicine

  14. Ecotourism (should have a balance between money and ecosystem) • Great Barrier Reef • Costa Rica • Fishing/Hunting Tourism and Recreation

  15. Biophilia: the need to connect with nature • Outdoor activities • People “need” this  Nature-deficit disorder • Children/people are spending less and less time outdoors Keeping in touch with Nature

  16. Closer to the mainland, increased biodiversity • Bigger island, increased biodiversity • Habitat fragmentation: • The disruption of an organisms environment Island Biogeography
