Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the "natural" or "background" rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.16 Aug 2010

Is it true that 99.9 of all species are extinct?
Of all species that have existed on Earth, 99.9 percent are now extinct. Many of them perished in five cataclysmic events. According to a recent poll, seven out of ten biologists think we are currently in the throes of a sixth mass extinction.
How do we know 99 of species are extinct?
Scientists have no way of confirming how many species of animals have lived and are living because there just simply is too many. Even knowing what we know about how fossils are created and the extinction rate of current species, there is no way to be sure about how many species are extinct.19 Oct 2019
