Accelerated modern human–induced species losses: Entering the sixth mass extinction
The oft-repeated claim that Earth’s biota is entering a sixth “mass extinction” depends on clearly demonstrating that current extinction rates are far above the “background” rates prevailing between the five previous mass extinctions. Earlier estimates of extinction rates have been criticized for using assumptions that might overestimate the severity of the extinction crisis. We assess, using extremely conservative assumptions, whether human activities are causing a mass extinction. First, we use a recent estimate of a background rate of 2 mammal extinctions per 10,000 species per 100 years (that is, 2 E/MSY), which is twice as high as widely used previous estimates. We then compare this rate with the current rate of mammal and vertebrate extinctions. The latter is conservatively low because listing a species as extinc

Over the past 40 years, there has been a dramatic decline in fishery landings of an iconic Baltic Sea fish: the flounder. In the 1980s, the landings of the flounder fishery in the Gulf of Finland dropped by 90 per cent, a trend that was later confirmed by fishery-independent surveys.
