Life is increasingly enhanced due to increasingly advanced technology, science - technology works to serve human life. But along with that development is the consequence that in the future we humans have to suffer by a lack of awareness of environmental protection. The environment is what surrounds us, from lush green grass, long winding rivers or horizon-high mountains, all in the living world around us. But reality shows that humans are murderers who have robbed their own lives by making the environment increasingly polluted, especially in big cities and industrial centers. Every school is dying more and more due to a lack of awareness of protecting natural resources, indiscriminate deforestation that punctures the world's empty lungs or the littering, waste, toxic gases from factories and latrines. Industry out of the canals, and out to our atmosphere is an alarming affair. Environmental pollution has become a hot problem of humanity. The Summit held in Brazil in 1992 issued a call for the whole world to together protect the Earth - our planet, and build a green - clean - beautiful environment. In Vietnam, we have also issued policies to protect natural resources and are ready to cooperate with countries around the world to protect the environment. Our students must also be conscious of maintaining environmental sanitation, actively participating in movement activities such as "green Sunday", school cleaning, neighborhoods, participating in planting trees and causing forests, not exhausting. litter in public places… In short, protecting the environment is protecting our own lives.
