What does the big tree do?

1. Photosynthesis: Because trees photosynthesize with sunlight, they can absorb carbon dioxide in the air and release oxygen. So ... whenever we walk into the Woods, there is a fresh air coming to our nostrils.

2. Regulate climate: The number of trees is an important indicator of environmental stability in a region. If there are enough trees in this area, the stability of the environment will not be bad. Where there are many trees, some natural disasters will be reduced and the air will be fresher.

3. Protective function: Big trees can also make cities and villages less affected and even protected from sandstorms. Many people write metaphors and write trees like umbrellas. I don't think this metaphor is exaggerated. Trees are the umbrella of our earth.

4. Making furniture: Trees are corrosion-resistant and waterproof materials. For our daily furniture use, it is best to use natural materials. People also like to use pure wood furniture, and special wood will also release special smells.
