  1. KEY CONCEPT The impact of a growing human population threatens biodiversity.

  2. Preserving biodiversity is important to the future of the biosphere. • Why biodiversity is important: • loss of medical and technological advances • extinction of species • loss of ecosystem stability

  3. Loss of habitat eliminates species. • Habitat fragmentation prevents an organism from accessing its entire home range. • occurs when a barrier forms within the habitat • often caused by human development

  4. corridors can be road overpasses or underpasses • allow species to move between different areas of habitat • Habitat corridors are a solution to the problem.

  5. Introduced species can disrupt stable relationships in an ecosystem. • An introduced species is one that is brought to an ecosystem by humans. • accidental • purposeful • Invasive speciescan have anenvironmentaland economicimpact.

  6. Burmese python (Florida Everglades) • Invasive species often push out native species.

  7. mice (Australia) • Invasive species often push out native species.

  8. kudzu (southeastern United States) • Invasive species often push out native species.
