The second phase of the Fifteenth Conference of the Parties of the United Nations Convention on Biological Diversity was held in Montreal, Canada from the 7th to the 19th of this month. On the 9th local time, World Union for Conservation of Nature updated the red list of endangered species, adding marine species including abalone , dugong , columnar corals, etc.

World Union for Conservation of Nature announced on Montreal on the 9th that more than 1,550 of the 17,900 marine species evaluated are at risk of extinction. At least 41% of these threatened marine species suffer from climate change. According to the updated Red List of Endangered Species, nearly 10% of the marine species evaluated are at risk of extinction.

The World Union for Conservation of Nature also evaluated the survival status of abalone for the first time and found that 20 of the 54 types of abalone around the world are at risk of extinction. The main problems facing abalone are unsustainable harvesting, illegal fishing, and climate change.

The new red list of endangered species also shows that the number of columnar corals in Caribbean has dropped sharply by more than 80% since 1990, and the threat level has jumped from "vulnerable" to "endangered" and has been directly upgraded to "extremely dangerous". In recent years, a highly contagious "stone coral tissue loss disease" has emerged, and the infection of large areas of columnar corals is the most urgent threat it faces.

In addition, due to the threat of accidental injury and poaching by fishing boats, the prototype of mermaid - the marine herbivorous mammal dugong is a "vulnerable" species worldwide, while dugongs living in the waters near East Africa and the waters near New Caledonia in the South Pacific have been upgraded to "extremely dangerous" and "endangered" respectively. The latest research found that the number of adult dugongs in the waters near East Africa has dropped to less than 250, while the number of adult dugongs in the waters near New Caledonia is less than 900.

It is reported that the IUCN Red List is a relatively authoritative list of species extinction risk assessments. The latest red list includes more than 150,000 species, of which 42,000 species are under threat.
