What s in the forest? What is the forest?

1. Forests are purifiers of the air. With the rapid development of industrial and mining enterprises and the rapid increase of fossil fuels for human life, the polluted air is mixed with a certain amount of harmful gases, threatening human beings, among which sulfur dioxide is a widely distributed and harmful harmful gas. All living things have the ability to absorb sulfur dioxide, but the rate and ability to absorb it are different.

Plants have a huge leaf area and absorb much more sulphur dioxide than other species. It has been determined that forest air contains 15-50% less sulphur dioxide than open land. In the summer of high temperature and humidity, the absorption rate of sulfur dioxide by the forest will increase with the vigorous physiological activity of the forest.

The relative humidity is above 85%, and the forest absorbs sulfur dioxide 5-10 times faster than the relative humidity of 15%. 2. Forests have a natural epidemic prevention function. Trees can secrete very lethal fungicides, kill germs and microorganisms in the air, and have a certain health care effect on human beings.

Bacteria in cubic meters of air have been measured in different environments: 1,000 in parks with crowds, 30,000 to 40,000 in downtown areas, and only 55 in forested areas. In addition, the amount of fungicide secreted by trees is also considerable.

For example, one hectare of juniper can secrete 30 kilograms of fungicide per day, which can kill germs such as diphtheria, tuberculosis, and dysentery. 3. Forests are natural oxygen plants. Oxygen is the basic condition for human beings to sustain life, and the human body has to breathe oxygen and excrete carbon dioxide all the time.

It is common knowledge that a healthy person who does not eat or drink for three or two days will not be fatal, but a short few minutes of lack of oxygen will die. It is documented that in order for a person to survive, he needs to inhale kilograms of oxygen and excrete kilograms of carbon dioxide every day. Forests absorb large amounts of carbon dioxide and release oxygen as they grow.

Studies have determined that for every 44 grams of carbon dioxide absorbed by trees, they emit 32 grams of oxygen. The leaves of trees produce one gram of glucose through photosynthesis, which consumes all the carbon dioxide contained in 2,500 liters of air. Theoretically, for every cubic meter of wood grown in a forest, it absorbs about 850 kilograms of carbon dioxide from the atmosphere. During the peak tree growing season, one hectare of broadleaf forest can absorb one tonne of carbon dioxide per day and produce 750 kilograms of oxygen.

According to the data, 10 square meters of forest or 25 square meters of grassland can absorb all the carbon dioxide breathed by a person and supply the oxygen needed. It is true that trees also have the characteristic of absorbing oxygen and excreting carbon dioxide at night, but because the amount of carbon dioxide inhaled during the day is very large, almost 20 times that of the night, compared to the *** at night, it is very small. Globally, forests and green spaces process nearly 100 billion tons of carbon dioxide for humans every year, provide 60% of clean oxygen for the air, and absorb suspended particulate matter in the atmosphere, which has the ability to greatly improve air quality. It can also reduce greenhouse gases and reduce thermal effects.
