Reforestation is the practice of planting trees in an area that has been deforested or degraded in order to restore its ecological function and increase biodiversity. This process helps to mitigate climate change by sequestering carbon dioxide from the atmosphere, as trees absorb carbon during photosynthesis. Reforestation projects can range from small-scale community planting efforts to large-scale commercial operations, and can be implemented in a variety of ecosystems including forests, wetlands, and grasslands. The goal of reforestation is to create a healthier and more resilient environment for both wildlife and people.
