Question 3.
Just think-what if there are no forests?
Answer:
Forest is the lifeline of our world, without them we cannot even imagine the wheel of life on earth. The list of trees served to our planet is very long-they absorb the carbon released by humans and other animals, they work to maintain the soil layer on the ground, they are also important in the regularization of the water cycle. Contribute, with this, trees provide food to nature and human species. Apart from this, they give shelter to countless creatures of the world. In the form of construction material i.e., wood, they also help humans to build their homes.

Trees are of such use to us, yet we keep them cut down ruthlessly, as if they have no utility for this earth. If we cut off all-the trees present on the earth, then no situation can be imagined except from the Holocaust. We must be living on a land that will not support life. The world will be so terrible that even a living being cannot be imagined to five there. Along with trees, most of the life on the earth will end, creatures living in the forest will also die, which are dependent on trees. There will also be a big change in the Earth’s climate.
