IUCN Updates Red List: Arctic Seals and Bird Species Face Increasing Extinction Threats
The International Union for Conservation of Nature (IUCN) has updated its Red List of Threatened Species, highlighting increased threats to Arctic seals and birds. Habitat loss from logging and agriculture is the primary threat to birds, while Arctic seals are suffering from global warming and reduced sea ice. The hooded seal's status has moved from vulnerable to endangered. Global warming in the Arctic is occurring four times faster than elsewhere, drastically affecting "keystone species" like ice-dependent seals that are central to the food web. On a positive note, the green turtle population has shown recovery due to long-term conservation.
Key Points
- The IUCN Red List now includes 172,620 species, with 48,646 threatened with extinction.
- Arctic seals are classified as 'keystone species' because they recycle nutrients and serve as a primary food source for other animals.
- 61% of bird species worldwide have declining populations, largely due to tropical forest destruction.
- The status of the hooded seal has been downgraded to 'Endangered,' while bearded and harp seals are now 'Near Threatened'.
Exam Facts
- The IUCN Red List update was released at the World Conservation Congress in Abu Dhabi.
- Arctic warming is occurring four times faster than the global average.
- Green turtle populations recovered by 28% since the 1970s due to sustained conservation.
