Now, the problem of population is a complicated one. Currently, the population of the whole earth has increased to an extreme, making it impossible for the earth to resist, so the natural resources are also likely to be insufficient at present, but fortunately, The governments of each country have come up with methods to deal with, but not yet, the corona virus appeared, causing the earth's population to be significantly reduced because they died in infection with covid 19.But no matter what, governments are still trying to come up with measures to prevent the epidemic to be able to stop the problem of the rapidly decreasing population and now, there are many ways to cure everyone. but still need a vaccine, scientists are in the process of creating a vaccine, they are the ones who hold the lives of humanity. So the problem of population is not only increasing but also decreasing horribly.

Life is increasingly improved due to increasingly advanced scientific and technological works to serve people's lives. But along with that development is the consequence that in the future we humans will have to suffer because of the lack of awareness about protecting the environment. The environment is what surrounds us, from the lush green grass, the long winding rivers or the high mountains to the horizon, all in a world that is living around us. But the reality shows that people are murderers who have taken their own lives by making the environment increasingly polluted, especially in big cities and industrial centers. Every school is dying day by day due to the lack of awareness of protecting natural resources, the indiscriminate deforestation that punctures the world's lungs or the dumping of garbage, waste, toxic gases from factories, Invasion into our canals, and out into our atmosphere is an alarming matter. Environmental pollution has become a hot issue of mankind. The Summit held in Brazil in 1992 made a call for the whole world to come together to protect the Earth - our planet, to build a green - clean - beautiful environment. Vietnam has also issued policies to protect natural resources and is ready to cooperate with countries around the world to protect the environment. Our students must also be aware of environmental hygiene, actively participate in movement activities such as "green Sunday", general cleaning of schools and neighborhoods, participating in planting trees to cause forests, not discharge Indiscriminate garbage in public places… In short, protecting the environment is protecting our own lives.
