What percentage of the earth's land area do biodiversity hotspots cover?

Step-by-step solution

These hotspots are also regions of accelerated habitat loss. Three of these hotspots – Western Ghats and Sri Lanka, Indo-Burma and Himalaya – cover our country’s exceptionally high biodiversity regions. Although all the biodiversity hotspots put together cover less than 2 per cent of the earth’s land area , the number of species they collectively harbour is extremely high and strict protection of these hotspots could reduce the ongoing mass extinctions by almost 30 per cent.
