Conservation International was a pioneer in defining and promoting the concept of hotspots. In 1989, just one year after scientist Norman Myers wrote the paper that introduced the hotspots concept, CI adopted the idea of protecting these incredible places as the guiding principle of our investments. For nearly two decades thereafter, hotspots were the blueprint for CI’s work.

Today, CI’s mission has expanded beyond the protection of hotspots. We recognize that it is not enough to protect species and places; for humanity to survive and thrive, the protection of nature must be a fundamental part of every human society.

Yet the hotspots remain important in CI’s work for two important reasons:

• Biodiversity underpins all life on Earth. Without species, there would be no air to breathe, no food to eat, no water to drink. There would be no human society at all. And as the places on Earth where the most biodiversity is under the most threat, hotspots are critical to human survival.
• The map of hotspots overlaps extraordinarily well with the map of the natural places that most benefit people. That’s because hotspots are among the richest and most important ecosystems in the world — and they are home to many vulnerable populations who are directly dependent on nature to survive. By one estimate, despite comprising 2.4% of Earth’s land surface, forests, wetlands and other ecosystems in hotspots account for 35% of the “ecosystem services” that vulnerable human populations depend on.
