What is the use of growing trees on a barren land?

Growing trees on barren land helps combat soil erosion, improves soil fertility, and enhances biodiversity by creating habitats for various species. Trees also play a crucial role in carbon sequestration, helping to mitigate climate change by absorbing carbon dioxide from the atmosphere. Additionally, they can improve local water cycles and provide resources such as timber, fruit, and shade, contributing to the livelihoods of nearby communities. Overall, reforesting barren land supports ecosystem restoration and promotes environmental sustainability.
