Benefits of planting trees
One. Trees regulate the climate and maintain ecological balance. Through photosynthesis, trees suck in carbon dioxide and spit out oxygen to make the air clean and fresh. An acre of forest gives off enough oxygen for 65 people to breathe for the rest of their lives.
Two. Trees can prevent wind and stabilize sand, conserve water and soil, and can also absorb various kinds of dust. An acre of forest can absorb various kinds of dust 20-60 tons a year.
Three. Trees can reduce noise pollution. The 40-meter-wide forest belt can reduce noise by 10-15 decibels. Noise pollution has caused great harm to human life, learning, work, and rest. It can be said that people are "enemies." "Noise can also cause humans to lose hearing, deafness, become stupid, and abnormal heart, blood pressure, and nerves in long-term life. It can even cause people to die from prolonged periods of noise.
Four. The secretions of trees can kill bacteria. There are 30,000 to 40,000 bacteria per cubic meter of air in the open space and only 300-400 in the forest.
Five. Trees can reduce temperature and increase humidity. For example, the temperature can drop to about twenty degrees at thirty degrees.
