How many hot spots of biodiversity in the world have been identified till date by Norman Myers ?

Options

A. 17
B. 25
C. 34
D. 43

Answer

**Step-by-Step Solution:**

1. **Understanding Biodiversity Hotspots**: Biodiversity hotspots are regions that are rich in endemic species (species not found anywhere else) and are under significant threat from human activities. These areas are crucial for conservation efforts.

2. **Norman Myers' Contribution**: Norman Myers is the ecologist who first identified these biodiversity hotspots. He conducted surveys to determine areas that meet specific criteria for being classified as biodiversity hotspots.

3. **Criteria for Hotspots**: To qualify as a biodiversity hotspot, a region must have:
- At least 1,500 species of vascular plants as endemics (which is about 0.5% of the total vascular plant species).
- It must be under significant threat from human activities, leading to habitat loss and fragmentation.

4. **Initial Identification**: Initially, Norman Myers identified 10 biodiversity hotspots based on his research and criteria.

5. **Current Count of Hotspots**: As of now, a total of **34 biodiversity hotspots** have been identified globally. These hotspots cover approximately 2.3% of the Earth's surface but are home to about 77% of the world's species.

6. **Importance of Hotspots**: The identification of these hotspots is essential for conservation efforts as they represent areas where biodiversity is both rich and at risk, making them a priority for protection.

**Final Answer**: Till date, **34 biodiversity hotspots** have been identified by Norman Myers.
