New red list of threatened species

According to the latest Red List of Threatened Species, more than 44.000 species are at risk of extinction, about 2.000 more than last year. The International Union for Conservation of Nature (IUCN) released the report on Monday during COP28 in Dubai. This year's list includes information on 157.000 species, about 7.000 more than last year's update.

Atlantic salmon, green sea turtles, scimitar-horned oryx... The Red List of Threatened Species updated on Monday highlights the impact of global warming on biodiversity and the results of conservation efforts.

The International Union for Conservation of Nature (IUCN) has published a new inventory of the global conservation status of threatened plant and animal species at COP28 in Dubai, United Arab Emirates.

The Red List, which measures the risk of extinction of future species, includes 157.190 species, of which 44.016 are globally threatened.

The new listing classifies green sea turtles that live in the central and eastern South Pacific oceans as "endangered" and "vulnerable," respectively, because they are also subject to global warming or accidental damage.

Botanically, "Honduran mahogany" or "big leaf mahogany", used to make furniture, ornaments and tools, has moved from "vulnerable" to "endangered" status. According to the IUCN, populations of this species in Central and Latin America have decreased by at least 60% in the last 180 years due to unsustainable agricultural practices, urban development and the expansion of agricultural land, which has led to the loss of tropical forests.

This update has improved the situation of two types of antelope

The scimitar-horned oryx is now considered "endangered" thanks to conservation efforts made through its reintroduction to Chad after it disappeared from the wild in the late 1990s. The IUCN added that its survival "depends on a continued protection against poaching.

The scimitar oryx is an antelope that lives in the subdesert regions of the Sahel, south of the Sahara.

Saiga antelopes, found primarily in Kazakhstan, are no longer "critically endangered" but are considered "near threatened." From 2015 to 2022, the Central Asian country's population increased by 1.100%.

The updated IUCN Red List of Threatened Species also summarizes the first global study on the status of freshwater fish species, which found that 25% of assessed species are now at risk of extinction.

Climate change is partly responsible for threatened species

This new report shows how climate change is exacerbating the planet's biodiversity crisis, making the environment more dangerous for thousands of species and accelerating the rapid decline of plant and animal populations on Earth.

"Species around the world are under enormous pressure. Everywhere you look, the number of threatened species is increasing"said Craig Hilton-Taylor, head of the IUCN Red List, an international organization that monitors the health of species.

What species are currently on the IUCN Red List?

Climate change is worsening the living conditions of some 6.700 endangered species. Salmon and turtle species are among those whose numbers are declining as the planet warms.

In the case of green sea turtles, as rising sea levels submerge their nests, fewer and fewer are born. turtles. Heating the water can damage their food source, algae.

Atlantic salmon are almost threatened, their population decreased by almost a quarter between 2006 and 2020

According to the IUCN, Atlantic salmon are not yet threatened, but their population fell by almost a quarter between 2006 and 2020. They are now considered near threatened. Fish live in fewer places and face man-made threats such as dams and water pollution. According to the group, climate change is making it more difficult to find food and increasing competition with exotic species. But there are some signs of hope: numbers increased in Maine, US, last year.

A quarter of freshwater fish species are at risk of extinction

The update provides the first comprehensive health assessment of freshwater fish species. A quarter of species (just over 3.000) are at risk of extinction.

As climate change causes sea levels to rise, salt water will move upstream. According to the IUCN, these species already face enormous threats from pollution and overfishing.

Frogs, salamanders and other amphibians are the most affected. Around 41% of these species are at risk of extinction.

"They are captives of the climate due to rising temperatures, drought... no matter what, amphibians cannot get away from danger and are directly affected by climate change"said Vivek Menon, vice-president of the IUCN Species Survival Commission.

We must all act to protect biodiversity

IUCN Director General Gretel Aguilar said it is clear that people must act to protect biodiversity and when conservation is done well, it is effective. She stated that to combat the threat of climate change it is necessary to phase out fossil fuels, which is a controversial issue at this year's COP28 negotiations.

"Nature is here to help us, so let's give back."I affirm.
