Answer :

Final answer:

Extinction rates currently range from about 100 to 1,000 species lost per day. E.O. Wilson has suggested that we may be losing approximately 30,000 species each year. This crisis is significantly accelerated compared to historical norms and is largely due to human influence.


Explanation:

Understanding Current Extinction Rates

Extinction rates are currently alarmingly high, with estimates suggesting that between 100 and 1,000 species are lost each day. This is a dramatic increase compared to the historical background extinction rate, which averaged just 1 to 10 species per year.

Harvard Biologist E.O. Wilson has projected that approximately 30,000 species are lost annually, which breaks down to about three species per hour or roughly 100 species per day. This is indicative of an ongoing biodiversity crisis primarily driven by human activities.
