The Chantal Massembo Foundation is a non-profit organization that carries out a vast reforestation program called "One House, One Tree," strongly inspired by the legacy of Wangari Maathai. The goal is to restore ecosystems while combating climate change. This approach is part of a community-based approach reminiscent of Wangari Maathai's Green Belt movement. Each family, each reforested home, is a step toward ecological resilience and social strengthening.
