Extinction Rates Have Slowed Across Many Plant and Animal Groups, Study Shows

Research led by scientists at the University of Arizona has revealed that extinction rates in plants, arthropods, and land vertebrates appear to have peaked around 100 years ago and have declined since then.

Around the world, many studies have suggested that the planet is currently experiencing a mass extinction, supported by evidence from extinctions in the past 500 years. However, this new study provides a more positive perspective.

‘We show that extinction rates are not getting faster towards the present, as many people claim, but instead peaked many decades ago,’ said Wiens.

Researchers found that past extinctions were mostly caused by invasive species on islands, rather than by today’s most significant threat to wildlife — the destruction of natural habitats.
