On the green leaves, water vapor like fog is emitted from time to time. This phenomenon of gaseous water evaporating into the atmosphere is called leaf transpiration. Plants need to transpirate about 300-400 kg of water to form 1 kg of dry matter.
The transpiration of plant leaves increases the humidity in the air, causing cloudy and foggy clouds, increasing rainfall, changing the environmental microclimate, and preventing drought. The transpiration of green plants can spit out fog and sow rain to subdue drought demons.
In recent years, scientists have discovered that the leaves of many plants can secrete fungicides, including pine, cypress, oak, eucalyptus, fir and so on. It has been determined that 1 hectare of pine forest secretes about 5 kg of volatile fungicides into the air every day and night. Cypress trees are more powerful in secreting up to 30 kilograms, and they can kill a variety of germs such as diphtheria, pulmonary laryngeal, dysentery, and many others.
As a result, the air in the taiga is particularly clean and fresh.
With the development of industry and agriculture, a large number of harmful gases are discharged in the production process, such as sulfur dioxide, hydrogen fluoride, etc. These harmful gases are absorbed by the leaves of some plants. For example, oleander leaves, in polluted areas, can absorb grams of sulfur per day.
Paulownia, sycamore, boxwood, etc. have a strong ability to absorb hydrogen fluoride and can also absorb chlorine. The leaves of these plants are nature's air purifiers.
To prevent noise, you also have to ask green leaves to help. It has been determined that a 40-meter-wide forest belt can reduce noise by 10-15 decibels, a 30-meter-wide forest belt can reduce noise by 6-8 decibels, and a large number of trees in urban parks can reduce noise by 26-43 decibels. Green streets, with lush foliage, can reduce noise by 8-10 decibels.

Green leaves are exposed to sunlight and synthesize inorganic substances (carbon dioxide and water) into organic substances, a process called photosynthesis. It is with this photosynthesis ability that green leaves can continue to produce food and store energy. It has been calculated that a person eats about 10,000 kilograms of sugar, 1,600 kilograms of protein and 1,000 kilograms of fat in his lifetime.
All organic matter, no matter how diverse it may be, whether you see it in a plant, in an animal, or in a person, they all pass through the leaves, and they all come from the substances made by the leaves. ”
For hundreds of millions of years, the photosynthetic products left over from plant photosynthesis, such as coal, oil, natural gas, etc., are very abundant and are the main energy sources on the earth. Due to the rapid development of industry, the people of the earth are facing the crisis of energy depletion. As a result, people are looking for ways to find new sources of energy.
At present, green energy has begun to play its miraculous role in production. People break down leaves, wood chips, etc., into sugars through a process called cellulase, which can be converted into new fuels for the benefit of mankind.
