Environmental problems associated with the forest?

Forest zones are no less important to the life of the planet than water. They provide humanity with oxygen, while purifying the air from pollution. At the same time, the normal life of forests is threatened by a number of environmental problems:

Climate change, namely the excessively scorching sun in the summer months, severe frosts in winter and a huge amount of rainfall. These changes are caused by chemical emissions into the atmosphere.
Uncontrolled deforestation.
Pollution of forests with human waste, especially plastic and metal waste.

All this affects the growth of trees and their functioning.
