The benefits that trees bring to mankind

Trees are common things around us. Many people just regard them as a kind of decoration in daily life, but trees have so many benefits for us. Trees can help us purify the air and prevent wind. Not only that, many daily necessities in our daily life are produced by trees. Trees have many benefits for everyone. Almost many things around us are realized by trees. Here is an explanation of the benefits of trees to humans. I hope it can help you have a clear understanding of trees.

1. Many trees can secrete bactericides to kill various pathogens in the air. They can also absorb toxic gases emitted by industrial production, retain smoke and dust that pollute the atmosphere, and eliminate noise pollution that is harmful to humans.

2. The tree kingdom can improve the quality of the environment on which human beings depend for survival. The tree kingdom and green plants are constantly carrying out photosynthesis, consuming carbon dioxide from trees and producing fresh oxygen; more than 60% of the oxygen in the air comes from trees and green plants on land.

3. In summer, people feel very different in the shade and in direct sunlight. People feel cool under the shade of trees in summer. This is because the dense green leaves of the tree can block the sunlight and absorb the sun's radiant heat, thereby lowering the temperature in the small environment. Trees are like huge pumps. They continuously absorb moisture from the soil into the tree body, and then diffuse most of the moisture absorbed by the roots into the atmosphere in the form of water vapor through the transpiration of the leaves, thus improving and regulating the relative humidity in the air.

4. The tree kingdom can also play an important role in protecting the environment on which human beings depend for survival. We know that strong winds can increase soil evaporation, reduce soil moisture, and cause soil wind erosion. In severe cases, sandstorms can bury towns and farmland. According to statistics from the United Nations in 1984, 6 million hectares of land are buried by sand every year, and one-third of the world's land is in danger of desertification. The United Nations called on the international community to fight to stop desertification in some parts of the world. "If you want to stop the sandstorm, you need to plant more trees."

5. Trees in mountainous areas where there are few trees are prone to form a miserable scene of "droughts make people look forward to rain, but when rain comes, it washes away all the fertilizer and soil, leaving only stony eggs." The uneven crowns and branches of trees can intercept and block rainwater, reduce the intensity of showers, and effectively prevent soil erosion to conserve water resources. This is the reason why people often say "picturesque mountains and clear waters" and "green mountains and clear waters".

6. The tree kingdom brings us not only food, timber, housing and jobs, but more importantly, the tree kingdom brings significant ecological benefits to the environment on which human beings depend for survival. This is something that nothing else can do; this is something that nothing else can replace.

7. Trees can regulate the climate, purify the air, prevent wind and noise, and prevent natural disasters such as soil erosion and landslides. They are oxygen manufacturers. One hectare of broad-leaved forest can absorb one ton of carbon dioxide and release 0.73 tons of oxygen per day.

8. Trees are dust filters. When a dust-laden airflow passes through a forest, as the wind speed decreases, the larger dust particles in the air will drop rapidly. In addition, some trees have hairs on their bark or can secrete oil, which can stick to dust, thereby greatly reducing the dust content of the air flow passing through the forest.

9. Trees are good at killing bacteria. Many trees secrete fungicides during their growth process, killing various pathogens brought by dust. According to the survey, the number of bacteria per cubic meter of air in department stores is 4 million, on boulevards is 580,000, in parks is 100, and in forests is only 55. The bacteria content in the air in the forest area and the department store differs by more than 70,000 times.

10. Trees can also increase greenery, beautify the environment, increase aesthetic value, and increase artistic elements, industrial value, wood, wood carvings and other wooden products. They also have medicinal value and can be made into medicinal materials. At the same time, the trees can reduce noise pollution. A 40-meter-wide forest belt can reduce noise by 10-15 decibels.

From this we can see that the tree kingdom and green plants are indeed of considerable value to human life, and are indeed a matter of life and death for us humans. How important is the existence of the tree kingdom to us humans! We must raise our level to look at the benefits that the tree kingdom brings to us humans. . If humans destroy trees, they are destroying their own homes.
