Environmental champion

Inna Modja is promoting the building of a wall across a continent, one that is designed to provide hope and bring people together. The Malian singer is starring in a documentary on the 8,000-kilometre Great Green Wall of trees and vegetation now being established across the width of Africa to combat desertification and restore land. She calls it a “world wonder” and says it has “great symbolism” that “extends far beyond the African continent”.
