2023 Audacious Project grantee Wanjira Mathai is at the forefront of re-greening the planet. Through the forest restoration initiative Restore Local, she's working to help both Africa's people and its landscapes flourish. Learn more about how her team invests in local restoration projects across the continent -- including a tree-growing movement that aims to revitalize 100 million hectares of African land by 2030. (This ambitious idea is a part of the Audacious Project, TED's initiative to inspire and fund global change.)
