Answer:
Forests and grasslands provide a wide range of ecosystem services. In addition to providing food, fuel and fibre, forests clean the air, filter water supplies, control floods and erosion, sustain biodiversity and genetic resources, and provide opportunities for recreation, education, and cultural enrichment. Forests regulate local and global climate, ameliorate weather events, regulate the hydro logical cycle, protect watersheds and their vegetation, water flows and soils, and provide a vast store of genetic information.
