What are the threats to biodiversity Wikipedia?
Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life. Rapid environmental changes typically cause mass extinctions.
