Today's life is increasingly enhanced by technological, scientific and technical works. But along with that development is the consequence that in the future we ourselves must suffer by the lack of awareness of environmental protection. Environment is what surrounds us; from the murmuring green forests, forever winding rivers or high mountain ranges to the horizon. But the reality shows that humans are the murderers who have robbed their own lives by polluting the polluted field more and more. Environmental pollution has become a hot issue for all mankind. Our students must also be aware of environmental sanitation. Actively participate in movement activities such as: "Green Sunday", cleaning schools, neighborhoods, participating in afforestation, greening bare hills, and not littering in public places. .. In short, each of us must be aware of preserving the environment so that the environment becomes greener - clean - beautiful.
