From my perspective, the forest resource is origin of creatures and a water resource. Furthermore, it has several benefits; for instance, it reduces the amount of carbon dioxide gas and increases that of oxygen gas which creates air freshness. Woods can prevent flooding damage by absorbing water. It protects soil collapse. It also adjusts ecosystem balance. Therefore, it is necessary that we should preserve it to fulfill it abundance. Although it is inevitable to destroy forest resource in some cases, we can replant trees.
