Assertion - Currently, approx. 35 biodiversity hot spots exist in the world. The reason is that 35 areas meet the requirements for becoming a hotspot. The large areas which contain exceptional concentrations of plant endemism and are experiencing very high rates of habitat loss are called ecological hot spots. These are also known as biodiversity hotspots. 2.3% of the Earth's land surface is represented by them.
Reason - An area must meet two strict criteria for becoming an ecological hotspot. Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as "endemic" species), Have lost at least 70 percent of its primary native vegetation. Thus, high level of species richness is a criterion for selection of a biodiversity hot spot.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
