The benefits of tree planting
1. Trees can regulate climate and keep ecological balance. Through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making the air clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe for a lifetime.
Walking in the forest, you will feel a rich fragrance, which is attributed to terpenes, which have strong bactericidal power. According to the determination, the content of bacteria in air per cubic meter is 4 million in department stores, 1 000 in parks and 55 in forests.
2. Trees can prevent wind and fix sand, keep water and soil, and absorb all kinds of dust. An acre of forest can absorb 20-60 tons of dust a year.
3. Woods can reduce noise pollution. Noise pollution has caused great harm to human life, study, work and rest, and noise will also weaken people's hearing in long-term life. Even, it can make people die under the long-term noise torture, and the forest belt with a width of 40 meters can reduce the noise 10- 15 decibels.
