Because flowers and trees are the green barriers of nature, we should take some protective measures instead of trampling on them. For example, chopping valves will cause a lot of soil erosion and so on.

2, winter protection measures

In winter, you can wrap the trunk with a rope to keep it away from the cold wind. At the same time, the thick layer around the trunk can also keep the trunk warm and avoid the trunk from cracking.

3. Don't pick leaves.

With the progress of the times, most people yearn for a green life. However, many people choose to swing on the branches in order to satisfy their inner desires. But this practice will cause serious damage to trees, such as leaves falling off and branches breaking. So don't swing on the branches!

4. Trees can keep ecological balance.

Because trees can inhale carbon dioxide and exhale oxygen through photosynthesis, they can make the air cleaner. According to the survey, one acre of forest can release oxygen for 65 people to breathe. It can be seen that trees and our human existence are closely related and inseparable.

5. Trees can prevent wind and fix sand.

Because the roots of trees need to be consolidated, they can inhale a lot of dust and keep the soil and water at the same time. It is understood that an acre of forest can inhale 20-60 tons of dust every year. In fact, in our daily life, it is very common for people to chop valves indiscriminately, so some places have also caused floods, mainly due to the loss of tree protection.

6. Other functions

There is no doubt that trees can also reduce noise pollution, and a forest belt 40 meters wide can reduce noise 10- 15 decibels; The secretions of trees can also kill bacteria. Generally, there are 30,000 to 40,000 bacteria per square meter in open space, while there are only 300 to 400 bacteria in forest. In addition, big trees can also reduce the temperature and improve the humidity!
