The primary factor driving extinction events in history has been significant environmental changes, often catalyzed by natural disasters, climate fluctuations, or geological events. These changes can disrupt ecosystems, leading to habitat loss, food scarcity, and increased competition among species. Additionally, anthropogenic factors such as habitat destruction, pollution, and overexploitation are currently accelerating extinction rates. Understanding the historical contexts of extinction events helps scientists predict future biodiversity declines and informs conservation efforts aimed at preserving vulnerable species and habitats in the face of ongoing threats.
