There are two trees, and there is a slogan hanging between them that it is everyone's responsibility to care for trees.

Look at the picture composition: It is everyone's responsibility to care for trees

On a big mountain, there is a big forest with lush foliage and fragrant flowers. Every morning, thousands of rays of sunshine pass through the dense cracks in the trees and shine on the earth. People often come here for a walk and exercise. Every day, you can see a peaceful scene in this big forest.

However, in this wonderful environment and atmosphere, there are some disharmonious pictures. One day, a lumberjack sneaked in, wearing a cap and holding a cigarette in his mouth. He looked flustered and looked around. He certainly didn't want others to find out his whereabouts.

He is a businessman. He is preoccupied with how to get rich and make a lot of money. One day, he heard that the price of wood had gone up, so he could sell it at a big price. So he picked up his big axe at home and went to the forest, where he carried out his secret operation unnoticed.

he looked around and walked around, trying to find a tall tree. Finally, he found a tall and strong tree in the depths of the forest. His eyes sparkled with greed and he ran quickly to the tree. He came to the tree and exclaimed, "Wow! What a big tree! It will definitely sell for a good price. " He raised his axe and chopped at the tree, singing: "La la la! La la la! I am an expert in cutting trees! " The sound of chopping trees woke up the woodpecker on the tree. It looked down and said, "This wooden head dares to destroy our home, and I want you to look good." Then he flew down, landed on the woodcutter's shoulder, pecked at the man's head hard, and said, "There must be insects in this piece of wood." The lumberjack screamed in pain, which attracted all the people nearby and sent him to the forest police station together.

The forest police taught him, "Even the woodpecker won't let you go. You must have worms in your head. The forest is not only the home of animals, but also the home of human beings. Trees are a gift of nature, shielding us from sandstorms and preventing soil erosion. Moreover, trees suck in carbon dioxide and provide fresh air for human beings. Trees are always silently contributing to human beings. You not only don't cherish and protect them, but also destroy and cut them down. It's really greedy! " After hearing these words, the woodcutter felt ashamed. From then on, he turned over a new leaf and became a volunteer to protect the forest.

Through this cartoon, we are also reminded that we should carefully protect the beautiful nature from any harm, and it is everyone's responsibility to care for trees, so that nature can better benefit our future generations. Trees are our friends. If they are cut down at will, there will be more and more carbon dioxide in the air, which will warm the earth and destroy the biological balance of the earth. Humans will not be able to survive. Let's all join the volunteer team to protect the big forests and protect our home on earth.

knowledge link: carbon dioxide is a non-toxic gas, which has no obvious harm to human body, but it can change the thermal balance of the atmosphere. The increase of carbon dioxide content in the atmosphere does not affect the solar radiation passing through the atmosphere. However, because carbon dioxide can absorb the infrared radiation of the earth, it will cause the temperature of the near-surface atmosphere to increase. The warming of the near-surface atmosphere will enhance the evaporation on the ground and increase the water vapor in the atmosphere. The increase of water vapor in the atmosphere will further enhance the absorption of infrared radiation from the earth in the near-surface atmosphere. As a result of this interaction, the increase of carbon dioxide in the atmosphere has changed the original atmospheric heat balance, resulting in global warming. Experts estimate that if the carbon dioxide content in the atmosphere increases by 25%, the near-surface temperature will increase by .5-2. degrees Celsius; If the carbon dioxide content in the atmosphere increases by 1%, the temperature near the ground will increase by 1.5-6. degrees Celsius. If this estimate is correct, the impact of carbon dioxide on the global climate can not be ignored after the mid-21st century.
