The correct Answer is:
To determine which option will cause the most severe depletion of biodiversity, let's break down the options provided: ### Step-by-Step Solution: 1. **Understanding Natural Extinction**: - Natural extinction refers to the process where species become extinct due to environmental factors such as habitat loss, natural disasters, and evolutionary changes. While it contributes to biodiversity loss, it is a natural process that occurs over long periods. 2. **Understanding Mass Extinction**: - Mass extinction is characterized by the loss of a significant proportion of species (about three-quarters) in a relatively short geological time frame. This can have drastic effects on biodiversity but is typically a rare event in Earth's history. 3. **Understanding Anthropogenic Extinction**: - Anthropogenic extinction is caused by human activities. This includes habitat destruction, pollution, overexploitation of resources, and species translocation. These actions can lead to rapid and severe declines in biodiversity. 4. **Comparing the Options**: - Natural extinction, while impactful, occurs over long time scales and is part of the natural cycle. - Mass extinction events, although severe, are infrequent and not currently ongoing. - Anthropogenic extinction is ongoing and is driven by human actions that are rapidly changing ecosystems and leading to the loss of species at an alarming rate. 5. **Conclusion**: - Among the options provided, anthropogenic extinction is the most severe cause of biodiversity depletion due to its immediate and widespread impact on ecosystems and species. ### Final Answer: The option that will cause the most severe depletion of biodiversity is **C. Anthropogenic extinction**.
