How is the ‘Sixth Extinction’ presently in progress different from the previous episodes?

The Sixth Mass Extinction is an ongoing event characterised by a significant decline in biodiversity and the extinction of numerous plant and animal species worldwide. Unlike previous mass extinctions, the current event is mainly caused by human activities, such as habitat destruction, climate change, and overexploitation of natural resources. The current extinction rate is estimated to be 100 to 1,000 times faster than in pre-human times. Ecologists warn that if the present trends continue, nearly half of all the species on Earth might be wiped out within the next 100 years.
