It is most important to arrange food for human life. Every person arranges their food in some way or the other from these tree plants. Some animals that humans eat also live by eating tree plants. In order to do farming the trees are cut and cleared from the forests in a very large area. To make land for cultivation, people even set fire to the forests so that the land can be completely cleared. We all know that forest fires prove to be very terrible and the environment suffers a lot of damage as well as a large amount of carbon dioxide is also released from this fire. Every part of the earth is populated. People have to do farming so that they can grow grains like wheat, rice and maize etc. to supply their food items. But even once people do not think that it is important to maintain balance. You cannot even guess how harmful it is to burn forests like this. Tree plants absorb carbon dioxide in our atmosphere and release oxygen. All of us have been studying these since childhood. They maintain the balance of the environment. That's why tree plants are the most valuable for human life. We humans clean the forests to meet our needs, whether it is for farming or for cutting and selling wood, for settling cities or for setting up industries. In every case, the cutting of trees invites global warming. By cutting such large number of trees, the proportion of carbon dioxide which the trees absorb and release the oxygen in the environment in turn is changing considerably. Now carbon dioxide is increasing and oxygen is decreasing due to which these greenhouse gas pollution is spreading very fast in our environment. When these tree plants are burnt, a lot of carbon dioxide is released from it. In this way from the harvesting of trees to the burning of trees, we have been calling nothing but global warming itself.
