Hot Spots
“25 hotspots contain the sole remaining habitats of 44% of the Earth's plant species and 35% of its vertebrate species, and these habitats face a high risk of elimination.”
“An aggregate expanse of 800,767 square kilometres, 38% of the hotspots total, is already protected in parks and reserves”
