India is the seventh largest country in the world in terms of total land area including land and water. Write the value of the land area of our country (in terms of percentage) of the world. Mention then, what makes India one of the 12 mega diversity countries of the world.

The correct answer is:
2.4 percent
8.1 percent share of the global species diversity

1. Land Area of India:
India is the seventh-largest country in the world, with a total geographical area of approximately 3.28 million square kilometers. When compared to the entire landmass of the Earth, India accounts for about 2.4% of the world's total land area.

2. Global Species Diversity Share:
Despite covering only 2.4% of the global land surface, India hosts a remarkably high percentage of the world's biodiversity. Specifically, it boasts an impressive 8.1% share of the global species diversity.

3. Why India is a Mega-Diversity Country:
A country is classified as a "mega-diversity" country if it exhibits high species richness and a high level of endemism (species unique to that specific geographic location). Because India supports about 8.1% of the world's species diversity on just 2.4% of the land area, it is recognized as one of the 12 mega-diversity nations of the world. This richness is driven by the country's diverse landscapes, which range from tropical rainforests and wetlands to deserts and alpine Himalayan ecosystems, hosting over 45,000 species of plants and nearly 90,000 species of animals.
