In recent decades, Vietnam has been entering the modernised and industrialised period, which leads to various changes. Besides some obvious advantages, it has undeniably been confronted with unprecedented environmental problems resulted from air and noise pollution, overpopulation and food and water source contamination. As the result, afforestation, cost-effective waste management system , birth-control and raising public awareness are strongly recommended as some of the most feasible solutions. Afforestation is considered to be one of the most effective ways to decrease air pollution by producing oxygen and carbon dioxide. “An approximate value for a 50-year-old oak forest would be 30,000 pounds of carbon dioxide sequestered per acre”, “ The forest would be emitting about 22,000 pounds of oxygen.” said Timothy J.Fahey, professor of ecology in the department of natural resources at Cornell University. Based on those numbers, it is obvious that forests play a fundamental role in the Earth since they brings lives to creatures including mankind.Their power, therefore, is used widely to tackle the air pollution of many countries. In Vietnam, forest cover density positively increased from 28% in 1942 to 41% in 2014( Thao Nguyen, November 26th ,2014), which brings an optimistic result to Vietnam’s environment. However, illegal logging and deforestation still exist. Marianne Brown’s article also said that: “Over the past 40 years, the country has lost 43 percent of its forest
