Cutting of trees or deforestation can never be justified. The trees take many years to grow from a sapling to a fully grown tree. It will take only a minute to decide to cut it down. But we need to seriously think about the aftereffects of cutting a tree before doing it. Trees give shelter and help to reduce the pollution by giving out the oxygen that we essentially need to breathe. If trees are not there, the atmosphere will face grave pollution. Global warming will also increase and in turn the climate in places will also change. The hole in the Ozone layer will also increase as a result of this. Understanding all this, we need to find alternate materials for the various demand for wood and save the earth by not cutting down trees, but to plant as many trees as possible in order to at least gift the future generation, a better Earth to live in.
