A new estimate finds that species die off as much as 1,000 times more frequently nowadays than they used to. That’s 10 times worse than the old estimate of 100 times. The previous estimate was one extinction per million species years, which skewed the current rate, making it appear to be only 100 times faster during human times. 2014-07-30 · The mutual dependence of all species is the most obvious reason to care about the current mass extinction crisis, and it is the one most often cited. In fact, if you read any articles or books regarding species extinction, it is likely the only reason mentioned. This concept has been thoroughly and eloquently explained many times before.

They also predict that future rates may be as much 2020-06-01 · Gerardo Ceballos González, a professor of ecology at the National Autonomous University of Mexico and one of the authors of the study, said approximately 173 species went extinct between 2001 and Most known species have small ranges. The numbers of small-ranged species are increasing quickly, even in well-known taxa. They are geographically concentrated and are disproportionately likely to Using the historical extinction rate to predict current rates of extinction is similar to using car crash numbers for Model T Fords in the 1920s to predict deaths on the road in the 2020s. the current annual rate of species extinction is up to ____ times the historical background rate of about ___. 1,000, 0.0001% has so few individual survivors that the species could soon become extinct Granted, extinction is a phenomenon that occurs naturally, however it normally happens at a rate of 1 to 5 species every year.

We also don’t know how many species we can afford to lose.

The rapid loss of species we are seeing today is estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate.* These experts calculate that between 0.01 and 0.1% of all species will become extinct each year.
