Current extinction rates are significantly higher than historical averages, primarily due to human activities. The ongoing loss of biodiversity is attributed to factors such as habitat destruction, pollution, climate change, overexploitation of resources, and the introduction of invasive species. These actions have accelerated the rate of species extinction well beyond the natural background rates observed in the fossil record. Historically, extinction rates have fluctuated due to natural events or shifts in ecosystems, but the current crisis is characterized by a rapid loss of species in a relatively short timeframe. Scientists estimate that current extinction rates may be up to 1,000 times higher than the background rate, suggesting an unprecedented biodiversity crisis primarily driven by anthropogenic factors. This urgent situation highlights the need for conservation efforts and sustainable practices to mitigate the loss of biodiversity.
