Answer:

hope its help u.....

Explanation:

Biodiversity hotspots host their diverse ecosystems on just 2.3% of the planet's surface,however, the area defined as hotspots covers a much larger proportion of the land. The original 25 hotspots covered 11.8% of the land surface area of the Earth. Overall, the current hotspots cover more than 16% of the land surface area, but have lost around 85% of their habitat.This loss of habitat explains why approximately 60% of the world's terrestrial life lives on only 2.3% of the land surface area.

There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot. About one-sixth of all plant species in the world live in this region. The New Zealand archipelago is another hotspot. Life on New Zealand evolved in isolation, so the islands contain many species not found anywhere else. More than 90 percent of the insects and 80 percent of the vascular plants in New Zealand are endemic to the region. The Himalayan region contains the tallest mountains in the world, as well as incredible animals found only there, including the giant panda, the wild water buffalo, and the black-necked crane—the only alpine crane in the world. Deforestation and climate change have made the Himalaya a biodiversity hotspot.

Answer 2

Explanation:

Biodiversity Hotspot is a region which is a prime location for the existence of rich biodiversity but also faces the threat of destruction. It is a place which needs our immediate and constant attention to survive and thrive in the future as well. This idea of identifying hotspots was put forth by Norman Myers in 1988.
