Mario Haberfeld used to race cars for Jaguar Brazil Racing. Today he champions the conservation of jaguars in Brazil and around the world.
Haberfeld's charity, Onçafari, has pioneered a way to reintroduce jaguars into the wild. A successful project in Brazil’s Pantanal, the world’s biggest wetland, has also brought an ecotourism boom to the area and given the world a blueprint for big cat conservation. Here’s how they did it.
Mário Haberfeld is a Schwab Foundation for Social Entrepreneurship Social Entrepreneur of the Year 2026, one of 21 innovators recognized this year for their work in driving systemic change around the world.
