What is the importance of 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. A 40-meter-wide forest belt can reduce noise 10- 15 decibels. 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 secretions 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.

Utilization and protection

Forest resources are an important part of natural resources. The utilization of forest resources is constantly changing with the development of human social productive forces. In agricultural society, human beings collect firewood from forest firewood as energy, and cut down wood to build palaces, temples and houses; In industrial society, human beings obtain wood from forests for papermaking, furniture, vehicles, boats and building materials.

In contemporary society, human beings use forest resources not only to obtain forest products, but also to play its role as an ecological barrier and provide people with places for leisure and entertainment. However, forest resources are limited, and unreasonable logging will cause ecological disasters. Therefore, dealing with the contradiction between economic growth and environmental protection and establishing a forest protection system is the premise to ensure the sustainable and efficient utilization of forest resources.

First of all, according to the characteristics of forest resources and the conditions of regional economic development, the development and utilization plan of forest resources should be formulated, and the structure and layout of forestry production should be arranged reasonably. Secondly, it is necessary to enact laws to protect forests, enforce the rule of law, severely punish deforestation, and limit the number and methods of logging.

The Forest Law of People's Republic of China (PRC) stipulates that forest logging shall be subject to quota management and logging license system, and proposes to strengthen the protection and management of forest resources, and establish and improve the "three defenses" system of forest fire prevention, pest control and illegal logging. Finally, establish nature reserves to protect forest animal and plant resources.
