Restoring forest cover through reforestation or afforestation involves planting trees to restore or create forests, helping rebuild ecosystems and fight climate change. Reforestation focuses on areas where forests were lost, while afforestation establishes new forests on previously barren land. Both approaches absorb carbon dioxide, protect soil, regulate water cycles, and support biodiversity. They also offer social benefits such as jobs and sustainable resources. However, success depends on planting native species and avoiding harmful monocultures.
