Brazilian photographer Sebastião Salgado and his wife, Lélia Deluiz Wanick Salgado, have been instrumental in reforesting the Rio Doce Basin area in Brazil since 1998. Through their organization, Instituto Terra, they have planted over 2.7 million trees, successfully restoring more than 550 acres of forest and 2,000 natural springs. 
Their efforts have transformed a once barren landscape into a thriving forest ecosystem, demonstrating the profound impact that dedicated reforestation initiatives can have on environmental restoration.
