What are the benefits of trees?

1. Trees can purify the air and provide oxygen. Trees in nature carry out photosynthesis every day, releasing a lot of oxygen, which is what people need most in their lives. Moreover, trees can purify the surrounding air, absorb dust and provide us with shade and light.

2. Trees can absorb dust. 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 quickly fall on the leaves. In addition, some trees have fur on their skins, and some can secrete oil, which can stick dust to leaves, thus reducing the dust in the air and purifying the air.

Trees can prevent desertification. Trees can also prevent desertification, as we all know, because sometimes continuous heavy rain will wash away a lot of soil on the ground, leading to desertification, and the roots of trees are very strong, which can firmly fix the surrounding soil and prevent soil erosion.
