What are the benefits of big trees to human beings?

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.

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. A 40-meter-wide forest belt can reduce noise10-15db. Noise pollution has caused great harm to human life, study, work and rest, and can be said to be people's "enemy".

Therefore, we should pay more attention to afforestation. Noise can also lead to hearing loss, deafness and stupidity, as well as heart, blood pressure and nerve abnormalities in long-term life. Even, it can make people die under long-term noise. In this way, the forest can reduce the noise by four or five times.

The secretion of trees can kill bacteria. There are 34,000 bacteria per cubic meter of air in the open space, and only 300-400 bacteria in the forest. Planting trees is the obligation of every citizen, and the state has designated March 12 as Arbor Day. Planting trees is of great benefit to our study, work and life.

5. Trees can lower the temperature and increase the humidity. At 30 degrees, the temperature can be reduced to about 20 degrees.

6. The Flower and Tree Empire brings us not only food, wood, houses and jobs, but also the great environmental benefits that the Flower and Tree Empire brings to the natural environment on which human beings depend. This is something that nothing else can do; Nothing else can replace it.

7. Flowers and trees can adjust the climate, purify indoor air, prevent wind and noise, and avoid floods such as soil erosion and landslides. They are carbon dioxide production plants. 1 hectare of broadleaf trees 1 day can digest and absorb 1 ton of carbon dioxide and release it.

0.73 tons of carbon dioxide.

8. Flowers and trees are devices for filtering smoke. When a cyclone with a lot of dust passes through a mountain forest, with the decrease of wind power, the dust with larger particles in the air will decrease rapidly. In addition, some flowers and trees have fur on their skin or can metabolize vegetable oil, which can stick smoke to their bodies, thus greatly reducing the dust content of cyclones passing through mountains.

9. Enjoy the cool under the big tree; The root system is developed, which can catch more soil;

10, with large canopy area, which can shelter from rain;

1 1 can attract many people to chat, enjoy the cool and play chess.
