Balance the ecosystem. In particular, in high mountainous areas, forests play the most important role because it can prevent landslides and prevent natural disasters.

There are many forests that have been severely damaged, so that in recent years, the situation of storms and floods has become more serious, the smoke generated from forest burning also causes serious air pollution.
