Northwestern Pakistan borders Afghanistan and for decades this region has been the scene of rebellion and armed resistance mixed with huge refugee camps. Three years ago, the local government started a “Billion Tree Tsunami” to fight deforestation and regenerate natural resources. The change has been drastic—even after, so far, only a few million trees have been planted. Previously arid hills are now covered with forest as far as the horizon. The new trees control against erosion, help mitigate climate change, decrease the chances of floods and increase the chances of precipitation.
