'To make matters worse, many of the animal species that are thought to be non-threatened from extinction, are in fact progressively declining'
Almost half of all life on Earth is “declining towards extinction... putting human wellbeing under increasing threat”, a grim new report from Queen’s University Belfast has found.
Catherine Finn, PhD student at Queen’s University Belfast and leading author on the research, said: “Almost half of animals on Earth for which assessments are available are currently declining. Up to now, the extent of this “extinction crisis” has been measured using “threat conservation categories” which the International Union for the Conservation of Nature assign to species upon assessment.The academics behind this groundbreaking research adopted a new approach using a global-scale analysis of a different measure of extinction risk called “population trends” to see whether the population sizes of species are declining, remain stable or are getting better over time.
Their research also found 33% of species currently considered “safe” by the IUCN conservation categories are in fact declining towards risk of extinction. “Geographically, we reveal an intriguing pattern similar to that of threatened species, whereby declines tend to concentrate around tropical regions, whereas stability and increases show a tendency to expand towards temperate climates.
