The current mass extinction is characterized by:
| 1. | The natural extinction of species as a result of environmental changes over millions of years. |
| 2. | The rapid loss of species in a relatively short period, primarily due to human activities. |
| 3. | A decrease in biodiversity due to the natural evolution of species. |
| 4. | The migration of species from their native habitats to new areas, leading to a decrease in local biodiversity. |
