Transcript of "Unit 16b Biodiversity and conservation"

  1. 1. KEY CONCEPT The impact of a growing human population threatens biodiversity. <br />
  2. 2. Preserving biodiversity is important to the future of the biosphere. <br />The loss of biodiversity has long-term effects.<br />loss of medical and technological advances. How?<br />extinction of species<br />loss of ecosystem stability<br />
  3. 3. Loss of habitat eliminates species. <br />Habitat fragmentation prevents an organism from accessing its entire home range.<br />occurs when a barrier forms within the habitat<br />often caused by human development. Like what?<br />
  4. 4. Habitat corridors are a solution to the problem.<br /><ul><li>corridors can be road overpasses or underpasses
  5. 5. allow species to move between different areas of habitat</li></li></ul><li>Introduced species can disrupt stable relationships in an ecosystem. How?<br />An introduced species is one that is brought to an ecosystem by humans.<br />accidental<br />purposeful<br />Invasive speciescan have anenvironmentaland economicimpact.<br />
  6. 6. Invasive species often push out native species.<br /><ul><li>Burmese python (Florida Everglades)</li></li></ul><li>Invasive species often push out native species.<br /><ul><li>mice (Australia)</li></li></ul><li>Invasive species often push out native species.<br /><ul><li>kudzu (southeastern United States)</li></li></ul><li>What invasive species do you know?<br />Lamprey eel<br />Lupine<br />Emerald Ash Borer<br />Kudzu<br />Zebra Mussel<br />Asian Lady Beetle<br />Gypsy Moth <br />
  7. 7. KEY CONCEPT Conservation methods can help protect and restore ecosystems. <br />
  8. 8. Sustainable development manages resources for present and future generations. Thinking sustainably involves thinking in ______ not in a ______.<br />Sustainable development meets needs without hurting future generations.<br />resources meet current needs<br />resources will still be available for future use<br />
  9. 9. The timber industry has started to adopt sustainable practices.<br /><ul><li>Global fisheries have adopted several sustainable practices.
  10. 10. rotation of catches
  11. 11. fishing gear review
  12. 12. harvest reduction
  13. 13. fishing bans</li></li></ul><li>Conservation practices focus on a few species but benefit entire ecosystems. How? <br />The Endangered Species Act works to protect individual species from extinction.<br />A listed species is often called an umbrella species. Why would it be called that?<br />the habitat in which the species lives must be protected<br />other species are protected because they share the ecosystem<br />
  14. 14. Protecting Earth’s resources helps protect our future. <br />The Environmental Protection Agency (EPA) was created in 1970.<br />The EPA develops policies and regulations to protect the environment.<br />Legislation helps to protect the environment and endangered species.<br />Clean Air Act<br />Clean Water Act<br />Endangered Species Act<br />
  15. 15. The National Park Service helps manage public lands. Name at least two national parks in the US.<br /><ul><li>The park system includes over 390 areas, covering 84 million acres.</li></li></ul><li>There are several ways that people can help protect the environment.<br /><ul><li>control population growth
  16. 16. develop sustainable technology and practices
  17. 17. protect and maintain ecosystems</li></li></ul><li>What causes smog? <br />A. the burning of particulates <br />B. the formation of ozone <br />C. acid rain <br />D. the interaction of sunlight with pollutants produced by burning fossil fuels <br />
  18. 18. What causes smog? <br />A. the burning of particulates <br />B. the formation of ozone <br />C. acid rain <br />D. the interaction of sunlight with pollutants produced by burning fossil fuels <br />Correct Answer = D<br />How is ground-level ozone formed? <br />A. coal particulates combine with oxygen molecules in the air <br />B. an oxygen atom is transferred from carbon dioxide to an oxygen molecule <br />C. an oxygen molecule is transferred from nitrogen oxide to an oxygen atom <br />D. an oxygen atom is transferred from nitrogen dioxide to an oxygen molecule <br />
  19. 19. What causes smog? <br />A. the burning of particulates <br />B. the formation of ozone <br />C. acid rain <br />D. the interaction of sunlight with pollutants produced by burning fossil fuels <br />Correct Answer = D<br />How is ground-level ozone formed? <br />A. coal particulates combine with oxygen molecules in the air <br />B. an oxygen atom is transferred from carbon dioxide to an oxygen molecule <br />C. an oxygen molecule is transferred from nitrogen oxide to an oxygen atom <br />D. an oxygen atom is transferred from nitrogen dioxide to an oxygen molecule <br />Correct Answer = D<br />
  20. 20. What is global warming? <br />A. the normal temperature fluctuations of Earth's climate cycle <br />B. the melting of the polar ice caps <br />C. the trend of increasing temperatures on Earth <br />D. the changes in Earth's biosphere that affect the atmosphere <br />Why are frogs considered an indicator species for water quality? <br />A. They are easily killed by direct contact with pollutants. <br />B. They are able to break down pollutants. <br />C. They come into direct contact with pollutants and show readily observed effects like deformities. <br />D. They develop diseases when they come in direct contact with pollutants. <br />

What is global warming? <br />A. the normal temperature fluctuations of Earth's climate cycle <br />B. the melting of the polar ice caps <br />C. the trend of increasing temperatures on Earth <br />D. the changes in Earth's biosphere that affect the atmosphere <br />Correct Answer = C<br />Why are frogs considered an indicator species for water quality? <br />A.

They develop diseases when they come in direct contact with pollutants. <br />Correct Answer = C<br />
  22. 22. Review<br />Preserving biodiversity helps the species and helps humans<br />Habitat corridors help preserve habitats<br />Avoiding invasive species introduction protects biodiversity<br />Sustainable development manages resources<br />Protecting individual species assists entire environments<br />The National Park system protects habitats for diverse species.<br />
