Why plant trees?

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.

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.
