Solution
- There are 34 highly sensitive biodiversity hotspots identified worldwide.
- These hotspots originally covered about 15.7% of the Earth’s land area.
- However, nearly 86% of these sensitive areas have already been destroyed due to human activities.
- At present, only about 2.3% of the Earth’s surface remains home to these biodiversity-rich regions.
- These hotspots contain around 1,50,000 plant species, which account for nearly 50% of the world’s plant species.
- In India, of the 135 endemic animal species, about 85 are found in the forests of the Eastern Himalayas and the North-Eastern region.
- The Western Ghats are home to approximately 1,500 endemic plant species.
- About 50,000 plant species worldwide are considered endemic, meaning they are found naturally only in specific regions.
- The biodiversity hotspots in India are as follows:
- The Western Ghats and Sri Lanka
- The Eastern Himalayas
- Indo-Burma
- Sundaland
