Great Green Wall and Environmental Issues

China's Great Green Wall is an ambitious project to combat desertification by creating a massive forest barrier. Initiated in 1978, it aims to transform desert areas into green spaces, using innovative techniques like fish scale pits and drought-resistant trees. The project has increased forest coverage and reduced dust storms, but faces challenges like water scarcity and monoculture risks. It serves as a model for global environmental efforts, inspiring similar initiatives worldwide.
