Hopefully, in the next 4 decades, we will see more of these kinds of transformations in the landscapes that have been affected by human activity. What can be seen in these images is the restoration of an ecological reserve that had been drying up during the last century in China. This initiative, called the “Great Green Wall” as a reference to the wall built back in the 7th century, aims to slow down and even reverse the desertification of the land by planting billions of trees throughout the area.
