What contribution do trees make to us? Speak in English and translate in Chinese.

Trees can adjust the climate, purify the air and eliminate wind noise. They are the best friends of human beings. Trees are oxygen factories. One hectare of forest can absorb one ton of carbon dioxide 1 day and release 0.73 ton of oxygen. Trees are dust filters. When the airflow containing a lot of dust passes through the forest, with the decrease of wind speed, the dust particles in the air will decrease rapidly at a greater speed. In addition, the epidermis of some trees has fluff or can secrete a kind of oil, which can adhere dust to the body, thus greatly reducing the dust in the air passing through the forest. The trees are being disinfected. Many trees can secrete killer factors during their growth, killing all kinds of pathogenic bacteria caused by dust. According to the survey, the number of bacteria in the air per cubic meter is 4 million in department stores, 580,000 in avenues, 100 in parks and only 55 in forests. The number of bacteria in the air is more than 7 times different from that in department stores. In addition, trees or natural reservoirs and natural air conditioning.

Trees can adjust the climate, purify the air, prevent wind and reduce noise, and are the best friends of mankind.

Trees are oxygen factories. One hectare of broad-leaved forest can absorb one ton of carbon dioxide and release 0.73 ton of oxygen in 1 day.

Trees are dust filters. When the airflow with large dust content passes through the forest, with the decrease of wind speed, the dust with large particles in the air will fall rapidly. In addition, some trees have fur on their skin or can secrete grease, which can stick dust to their bodies, thus greatly reducing the dust content in the airflow through the forest.

Trees are experts in sterilization. Many trees secrete fungicides during their growth, killing all kinds of germs brought by dust. According to the survey, there are 4 million bacteria per cubic meter of air in department stores, 580,000 in boulevards, 100 in parks and only 55 in forest areas. The difference of bacterial content in the air between forest areas and department stores is more than 70 thousand times. In addition, trees are natural reservoirs and natural air conditioners.
