The Red List, prepared by the International Union for Conservation of Nature (IUCN), which includes species threatened with extinction, was updated days before the end of 2023. The number of species assessed in the list, which was 73,686 in 2014, increased to 157,190 and the number of endangered species, which was 22,103 in 2014, increased to 44,16. According to the Red List, the big-toothed Lake Turkana robber (brycinus ferox), which lives in Lake Turkana in Africa, was included in the "vulnerable" category from the "least concern" category due to the degradation of habitats caused by climate change and overfishing. The population of Atlantic salmon (salmo salar), whose development and feeding process is adversely affected by climate change, decreased by 23 per cent between 2006 and 2020, which led to its status on the Red List being moved from "least concern" to "imminent threat".
