Forests play an important role in our daily lives by providing homes, the air we breathe, and many more. It also provides several essential resources including wood, fruits, timber, and many more in our daily lives. Forests also help in reducing several forms of pollutants such as air pollution, and many more. They also control or restrict the flow of water and help the earth to absorb which reduces property damage and soil loss during heavy floods. Forests are also beneficial in maintaining the temperature of the Earth and lowering the risk of global warming. They also help in maintaining the oxygen levels in the atmosphere which makes it easier for humans and several other creatures to breathe.

Forests also provide wood that can be used in making houses and beautiful furniture, and making food for human beings. But due to industrialization, deforestation is rapidly increasing which may result in enhancing global warming across the world that is harmful for human beings.

Thus, the main aim of this international day is to protect and conserve forests to maintain oxygen levels, promote afforestation that reduce global warming across the world.
