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