One of the best ways of cleansing the air is to plant trees, because they play an important role in maintaining clean air, releasing oxygen and absorbing carbon dioxide. The more trees, the higher the quality of the air, so they fit – this is the right step towards saving the environment . It is very important to take a stand against deforestation. The loss of large amounts of trees, when cutting down tropical forests for the benefit of the development of the industry, means that we lose millions of trees that would clean the air for us .
