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.

Genetic diversity, ecosystem diversity, and human-derived diversity are measures of biodiversity that currently define life on earth.

Biodiversity has been affected by five mass extinction periods, which greatly influenced speciation and extinction rates.

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.
