  1. Conserving Biodiversity Chapter 5 section 3

  2. Renewable Resources • Resources that can be replaced faster by natural processes • Examples: solar energy, agricultural plants, water, air • These things are not unlimited, if supply is greater than demand the resource could become depleted

  3. Nonrenewable Resources • Resources that are found on Earth in limited amounts OR that are replaced by natural processes over extremely long periods of time • Examples: fossil fuels, minerals

  4. Sustainable Use • Using resources at a rate in which they can be replaced or recycled while preserving the long term health of the biosphere • Conservation can include reducing the amount of resources that are consumed, recycling when possible, preserving ecosystems

  5. Protecting Biodiversity • Protected Areas in the US: State and National Parks and Nature Reserves; Ex. Yellowstone National Park • International Protected Areas: 7% of the worlds land is set aside as some type of reserve; http://www.science20.com/anthrophysis/new_method_identifying_habitats_need_conservation-88575

  6. Protecting Biodiversity • Biodiversity Hot Spots: locations around the world that are characterized by the high levels of Endemic Species (species that are found only in a specific geologic area) and critical levels of habitat loss • Must meet 2 criteria: at least 1500 species of plants that are endemic and the region must have lost at least 70% of its original habitat http://www.newyorkgoadiaries.com/2012/03/source-biodiversity-hotspots-website.html

  7. Protecting Biodiversity • Corridors Between habitat fragments: passages between habitat fragments so that organisms can still pass safely http://www.care2.com/news/member/100041282/2723566

  8. Restoring Ecosystems • Bioremediation: use of living organisms (such as prokaryotes, fungi or plants) to detoxify a polluted area (such as during an oil spill • Biological Augmentation: adding natural predators to an ecosystem (ex: aphids destroys crops and lady bugs eat aphids. Introduce ladybugs to an ecosystem to lower number of aphids)
