The global assessment of freshwater animals on the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species evaluated the extinction risk of 23,496 freshwater ...
“Most species don’t have just one threat putting them at risk of extinction, but many threats acting together,” said Sayer, a study-co-author. The tally, published in the journal Nature, is the first that time researchers have analyzed the global risk to freshwater species. Previous studies have focused on land animals including including ...
The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit; [17] nearly 2,000 species were added, [18] with 4 species to the extinct list, 2 to the rediscovered list. [19] The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Twenty-five percent of plant and animal species are threatened with extinction. [17] [18] [19] In a subsequent report, IPBES listed unsustainable fishing, hunting and logging as being some of the primary drivers of the global extinction crisis. [20] In June 2019, one million species of plants and animals were at risk of extinction.
Populations of the vulnerable species of marine mammal, numerous species of abalone and a type of Caribbean coral are now threatened with extinction, an international conservation organization ...
Of North American freshwater species, an estimated 48.5% of mussels, 22.8% of gastropods, 32.7% of crayfishes, 25.9% of amphibians, and 21.2% of fish are either endangered or threatened. [24] Extinction rates of many species may increase severely into the next century because of invasive species, loss of keystone species, and species which are ...
Eight of the extinct bird species were found in Hawaii, including the Po`ouli, which was last seen in 2004. The Po`ouli is the most recently seen species of all 21 animals on the list.
