Explain how the protection of biodiversity hotspots alone can reduce up to $30 \%$ of the current rate of species extinction.

(N/A) Biodiversity hotspots are regions with very high levels of species richness and high degree of endemism.
Although all the biodiversity hotspots put together cover less than $2 \%$ of the Earth's land area,the number of species they collectively harbor is extremely high.
By strictly protecting these hotspots,we can prevent the loss of a vast number of endemic species.
Therefore,strict protection of these hotspots could reduce the ongoing mass extinctions by almost $30 \%$.
