What role does the forest play in human life?

The forest plays a huge role in human life. First of all, these are the lungs of the planet, because up to 40% of oxygen on Earth is produced by trees, the rest is phytoplankton. Also, the forest is a source of wood for human needs, which is used both for domestic needs and for the needs of the chemical and other industries. Do not forget that forests are the most important element of the ecological system of the planet and, in addition to direct influence, have an indirect effect on human life.
