Step-by-step explanation:
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.[1][2]
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.[1][2]Norman Myers wrote about the concept in two articles in “The Environmentalist” (1988),[3] and 1990[4] revised after thorough analysis by Myers and others “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions”[5] and a paper published in the journal Nature.[6]

Some of these hotspots support up to 15,000 endemic plant species and some have lost up to 95% of their natural habitat.[7]

Some of these hotspots support up to 15,000 endemic plant species and some have lost up to 95% of their natural habitat.[7]Biodiversity hotspots host their diverse ecosystems on just 2.4% of the planet's surface,[2] 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.[1] Overall, the current hotspots cover more than 15.7% of the land surface area, but have lost around 85% of their habitat.[8] This loss of habitat explains why approximately 60% of the world's terrestrial life lives on only 2.4% of the land surface area.
