How many hotspots of biodiversity in the world have been identified to date by Norman Myers?
A. 34
B. 43
C. 17
D. 25
Solution
The concept of biodiversity hotspots was developed by Norman Myers in 1988. Hotspots constitute just 2.3 percent of the Earth's overall surface area. These hotspots are important as all life on Earth is underpinned by biodiversity.
Complete answer:
A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. Biodiversity hotspots are defined as regions where exceptional populations of endemic species are subject to exceptional habitat loss. A hotspot is a natural habitat that has at least more than 0.5 percent of total vascular plants as endangered species and is affected by human action.
The idea of biodiversity hotspots was created by Norman Myers in 1988 when he described the depletion of habitat and plant species in the tropical forest. IUCN is planning the 'Red Data Book.' 34 regions around the world are known as Biodiversity Hotspots. These hotspots constitute just 2.3 percent of the Earth's overall surface area. These hotspots are important because all life on Earth is underpinned by biodiversity. Excluding species, there will be no breathing oxygen, no food to consume, no water to drink. There would have been no human civilization at all. And as areas on Earth, where the most wildlife is at risk, hotspots are important to human survival.
Hence, the correct answer is option A.

The Tropical Hotspot of the Andes Mountains is the most complex hotspot in the world. Approximately one-sixth of all plant species in the world live in this area. The archipelago of New Zealand is another hot spot. Life in New Zealand has developed in isolation, so the islands contain several animals not present anywhere else. New Caledonia is the smallest hot spot in the world. In India, there are four biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region, and the Sundaland (Includes a group of Islands). These hotspots include a variety of endangered species. There are four of the world's 36 biodiversity hotspots in India—the Himalayas, the Indo-Burma region, the Western Ghats, and the Sundaland. Hotspots are areas with a rich, diverse and endangered biodiversity.
Note: Biodiversity hotspots have multiple advantages, such as increasing the efficiency of the ecosystem; each species in the ecosystem has a particular niche, a role to play. Support a greater number of plant species and thus a larger range of crops. Protect the resources in freshwater. Promote the formation and preservation of soils.
