Biodiversity is dynamic and changes over time, influenced by speciation and extinction events. However, human actions—such as climate change and overexploitation—are increasing extinction rates. As extinction rates increase, ecosystems experience a loss in biodiversity.

The emerging field of biodiversity-ecosystem function (BEF) studies these interactions. Higher biodiversity spreads interactions among more species, reducing the chance of ecological collapse. Ecosystems with more species and interactions are less likely to suffer negative impacts from disturbances, as crucial components are less likely to be removed.
