what do scientists report on the current rate of extinction? Modern extinction rates average around 100 E/MSY. This means birds, mammals and amphibians have been going extinct 100 to 1000 times faster than we would expect. Researchers think this might even be an underestimate.
Why are scientists concerned about the current rate of extinction? The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
How do scientists calculate extinction rates? Scientists calculate background extinction using the fossil record to first count how many distinct species existed in a given time and place, and then to identify which ones went extinct.

How do African elephants impact the environment?
