How many species are there in the world? ——Inventory of hot topics and data in the past 10 days
In the era of information explosion, countless new topics emerge every day. This article will sort out the popular content on the Internet in the past 10 days and answer the question "How many species are there in the world" through structured data, covering diverse fields such as species, language, and culture.
1. Biodiversity: Statistics of global species numbers
According to the latest data from the World Conservation Union (IUCN), the number of confirmed species is as follows:
| category | Confirmed quantity | Estimated total |
|---|---|---|
| mammal | 6,495 species | About 7,000 species |
| birds | 11,188 species | 12,000-18,000 species |
| insect | 1,000,000+ species | 5-10 million species |
| plant | 391,000 species | About 450,000 species |
2. Human Civilization: Language and Cultural Diversity
UNESCO’s World Language Map shows:
| category | Existing quantity | Endangerment ratio |
|---|---|---|
| living languages | 7,151 species | 40% are on the verge of disappearing |
| world cultural heritage | 1,199 places | - |
| intangible cultural heritage | 730 items | - |
3. Technology Hotspots: Explosive Growth of AI Large Models
The Stanford AI Index report reveals:
| years | Number of newly released large models | main country of origin |
|---|---|---|
| 2021 | 15 | United States (12), China (3) |
| 2023 | 149 | United States (109), China (20) |
4. Internet Culture: The Global Evolution of Emojis
New data from the Unicode Consortium in 2024:
| Version | Total number of expressions | Add category |
|---|---|---|
| Unicode 15.1 | 3,782 | Directional gestures, wildlife |
| 2024 Draft | Expected to exceed 4,000 | AI related symbols |
5. Economic Observation: Global Currencies and Cryptocurrencies
| currency type | Circulation quantity | annual growth rate |
|---|---|---|
| fiat currency | 182 species | Stablize |
| cryptocurrency | 23,000+ species | 37%(2023) |
In-depth analysis:
1.Limitations of species cognition: The species that have been scientifically described currently account for only 20% of the estimated total, and the deep sea and rainforest are still blind areas for exploration.
2.language death crisis: On average, one language disappears every two weeks, and digital protection has become a hot topic.
3.AI ethics controversy: The surge in the number of large models has triggered discussions about computing power consumption and content security.
Future outlook:
As technology develops, humankind’s understanding of “categories” will continue to expand. The emergence of new categories such as metaverse assets and quantum matter will redefine the boundaries of taxonomy. Protecting existing diversity while responsibly creating new forms is a key proposition for the development of civilization.
