The International Union for Conservation of Nature (IUCN) warned on its red list this Saturday (4). 28% of 138,374 species The world’s already classified 38,543 species are threatened with extinction.
In short, according to the publication, they are threatened with extinction:
- 41% amphibian species;
- 33% coral reefs;
- 34% cones, mostly wood species;
- 26% of mammal species;
- 37% of shark and ray species
- 14% of bird species
Warning system for the protection of marine life
One of the highlights Komodo dragonsConsidered the largest lizard in the world and a World Heritage Site. The lizard’s classification went from “vulnerable” to “threatening”. This species is found only in Indonesia and only in the Komodo National Park. Due to climate change, rising sea levels are expected to reduce suitable Komodo dragon habitat by at least 30% over the next 45 years.
The red list also highlights Marine species, Be warned that 37% Sharks and Rays The ones listed in the world are in danger of extinction. In addition, overfishing is almost threatening Two of the five endangered sharks. Climate change is a bad indication for the loss and degradation of marine habitat.
On the other hand, this document reviewed seven species of tuna caught commercially and showed four more signs of recovery, thanks to countries that use sustainable fishing quotas and successfully combat illegal fishing. One is the Yellowfin Tuna, which has gone from “threatening” to “less anxious”.
“Today’s IUCN Red List update is a powerful indication that species can recover if nations truly commit to sustainable practices despite increasing pressure in our oceans,” said IUCN Director General Bruno Oberle.

30% of trees are endangered
The World Trees Status Report, released in August, found that At least 30% of the 60,000 known tree species are endangered. The warning relates to a total of 17,500 tree species, twice as many endangered mammals, birds, waterfalls and reptiles, and is based on IUCN data.
Brazil is the world’s largest biodiversity hotspot, with the highest number of tree species (8,847) and the most endangered tree species (1,788).

About 142 species in the survey have already disappeared from the forest and 442 are near extinction – in these cases, less than 50 individual trees of each species remain.
According to the study, the endangered tree species are diverse, ranging from the well-known oaks and magnolias found in our Amazon rainforests to tropical tree trees.

A study published in the September 1 issue of the scientific journal Nature, with the contribution of Brazilian scientists, revealed that the fire that has been hitting the Amazon since 2001 may have been affected. 95.5% of invertebrate plant and animal species are already listed throughout the biosphere. The scientists used data from the IUCN.
According to Nature, fires caused by human activity in the Amazon over the past 20 years have already affected the habitats of 85.2% of the flora and fauna, 53 of the 55 endangered species. அழிவு; 5 of the 9 endangered reptile species; Of the 107 amphibian species, 95 are endangered; And 236 of the 264 plant species are endangered.
Of the endangered mammals directly affected by the fire in the Amazon, this study gives examples of some types of marmosets and spider monkeys, as well as some birds such as the Murchison.
