Wildlife conservation often depends on projects that begin with strong local knowledge but struggle to secure funding beyond a few years. Around the world, many endangered animals survive because of small organisations working with limited staff, modest budgets and long-term commitment rather than high-profile attention.

Foundations funded by Leonardo DiCaprio and Jeff Bezos have launched a $200 million initiative to revive 100 of Earth's most threatened species.

Leonardo DiCaprio's Re:wild, which he co-founded with Dr. Wes Sechrest, and the Bezos Earth Fund are launching the Phoenix Species Project.
