i. Improvement of climate: The influence of forests on things like wind, temperature, rainfall, and humidity is improved. They control the water cycle, O2, CO₂ balance in the atmosphere, and temperature.
ii. Control of flood: Forests prevent flooding by minimising erosion on sloping hills and silting up in lakes, rivers, and other reservoirs.
iii. Aesthetic, recreational and development of tourism facilities: Any person, especially those who live in cities, can find
relief from their repetitive lives in forests.
iv. Conservation and development of wildlife including birds: In terms of shelter, a place to reproduce, and a supply of food, forests are the optimal environment for wildlife.
