For example, some people want to go the toilet, they should take a wrap of tissue paper or someone’s skin bleed the tissue is very useful. The tissue plays an important role in our life. Tissue is made from tree. I think it is not environmentally protection to the earth. Otherwise, the tree is cut by people and the air become much worse. So I think even though tissue is very important to us, but we should not waste this resource.
