Granted extinction is a phenomenon that occurs naturally however it normally happens at a rate of 1 to 5 species every year. The current extinction rate is approximately 100 extinctions per million species per year or 1 000 times higher than natural background rates.

But as scientists estimate we are currently losing species 1 000 10 000 times faster than that which means that literally tens of species are vanishing from the face of the earth every day.
Animal extinction rate graph. If so it may be the fastest one ever with a rate of 1 000 to 10 000 times the baseline extinction rate of one to five species per year. The iucn says at least 50 animals move closer to disappearing each year. Most of them occurred during the 1900s see charts below.
There is data showing that between 0 01 0 1 of all species are lost every year roughly 200 to 2 000 extinctions every year. Nearly 21 000 monitored populations of mammals fish birds reptiles and amphibians encompassing almost 4 400 species around the world have declined an average of 68 between 1970 and 2016. The rate of species extinction is up to 10 000 times higher than the natural historical rate.
Plant and animal extinctions are occurring at a rate of at least 1 000 times faster than the time before humans a new study says. This graph plots extinction rates of marine animal families over the last 600 million years. The starting date for the inclusion of extinctions into the charts was set at 1500 ad to be in line with the starting date used by the committee on recently extinct organisms.
The current rate of extinction is 1 000 to 10 000 times higher than the natural extinction rate. They also predict that future rates may be as much. Half of species in critical risk of extinction by 2100 more than one in five species on earth now faces extinction and that will rise to 50 by the end of the century unless urgent action is taken.
In the study published thursday by the journal science lead. Currently around 41 per cent of all amphibians and 25 per cent of all mammals are threatened with extinction. The shaded band indicates the normal range of extinction rates known as background extinction the.
Humans are largely responsible for the striking trend. The total number of known extinct species is 905 species.
