Greening has many benefits [conan0 1]

Now flooding, air pollution, noise and other problems seriously endanger human health, and more people die at their hands like demons. As the saying goes, "the magic is one foot high and the road is one foot high." The solutions to these problems boil down to two words: greening. Don't underestimate it, it has many benefits.

Greening means planting trees and grass. Planting these plants containing chlorophyll is of great help to improve air quality.

First of all, green plants can carry out photosynthesis in the sun, absorb carbon dioxide and release oxygen. Studies show that plants can produce 5 tons of oxygen per growth 1 ton. Each hectare of forest can absorb 1 ton of carbon dioxide every day and produce 0.735 ton of oxygen; Each hectare of grassland can absorb 0.9 tons of carbon dioxide and produce 0.6 tons of oxygen every day. Adequate and clean oxygen can keep people healthy.

Secondly, the forests on the earth can emit 654.38+700 million tons of terpenoids into the atmosphere every day, which has unparalleled bactericidal ability and exciting effect.

Then, green plants can filter and absorb the dust in the air, and can prevent the work dust from spreading into the air. According to the measurement, when the atmosphere passes through the forest belt, the amount of dust and floating dust can be reduced by 32%-52% and 30% respectively.

Do you know that?/You know what? Do you know that?/You know what? Forest negative oxygen ions can reach10-100000. Negative oxygen ions can regulate the excitation and inhibition of nervous system and improve the function of cerebral cortex. Medical experts simulate the magical effect of forests and introduce negative oxygen ions into wards. The results show that when the ratio of negative oxygen ions to positive oxygen ions in the environment is controlled at 9: 1, it can promote the treatment of patients with asthma, burns, ulcers and trauma.

In addition, greening can also absorb noise and reduce soil erosion. Put your share of strength into the greening of our country, and that touch of green will slowly tell you its benefits.
