Every day, three animal or plant species become extinct. Every day. Forever. This terrible process of constant annihilation is known as the "Sixth Great Extinction" and it's a real threat to our planet. How can humankind solve this great challenge? Scientists have come up with the ultimate solution: to create biodiversity hotspots. Where are these sanctuaries located? What species can be found in them? What are the main threats? These and other questions are the main theme of Hotspots: The Last Hope.
