- 47.1A: Loss of Biodiversity
- Human activity is the driving force behind the current biodiversity crisis, which is causing great species loss in a short time period.
- 47.1B: Types of Biodiversity
- Genetic diversity, ecosystem diversity, and human-derived diversity are measures of biodiversity that currently define life on earth.
- 47.1C: Biodiversity Change through Geological Time
- Biodiversity has been affected by five mass extinction periods, which greatly influenced speciation and extinction rates.
- 47.1D: The Pleistocene Extinction
- Biodiversity loss, especially the disappearance of megafauna, during the Pleistocene Extinction has been linked to the arrival of humans.
- 47.1E: Present-Time Extinctions
- Human activities probably caused the Holocene mass extinctions; many methods have been employed to estimate these extinction rates.
