They support the environment and provide many resources necessary for human survival. One of the greatest benefits of trees is that they purify the air. They release oxygen needed for breathing and absorb greenhouse gases such as carbon dioxide, helping to keep the atmosphere clean and healthy. Trees also help regulate temperature by providing shade and reducing heat, acting as natural coolers that make the surroundings more comfortable. Another key role of trees is protecting the soil. Their roots hold the ground firmly and prevent erosion during heavy rains. Forests also influence rainfall and help maintain ecological balance. In addition to their environmental benefits, trees provide valuable products such as timber, fuel, fruits, and medicines. Wood, for example, is widely used in construction and furniture. Therefore, planting and protecting trees is essential for a safe and sustainable future. SubQuestion No : 16
