Life has been improved by more advanced technology, science and technology works to serve human life. But along with that development is the consequence that in the future it is we who suffer from the lack of awareness of environmental protection. The environment is what surrounds us, from green pastures, long winding rivers or hills, all in a world around us. But the reality is that human beings are the killers who steal their lives by making the environment increasingly polluted, especially in big cities and industrial centers. Every school is dying due to a lack of awareness about natural resource protection, littering of the world's lungs, littering, waste, toxic gases from the factory making canals, and setting our atmosphere on the sidelines is alarming. Environmental pollution has become the hot issue of mankind. Vietnam has also promulgated natural resource protection policies and is willing to cooperate with countries around the world to protect the environment. Our students also have to be aware of environmental sanitation, actively participate in activities such as "green Sunday", general cleaning classrooms, neighborhood, participate in planting forest, do not discharge littering in public ... In short, protecting the environment is protecting our own lives.
