Trees remove 100 to 120 billion tons of carbon each year from man-made sources like (cars, trains, planes, etc). They moderate climate, improve air quality, conserve water and also harbor wildlife, trees cut down energy costs- air conditioning and heating costs are lower in shaded areas. The less energy used by consumers the less CO2 emissions in the atmosphere. According to DeRosa’s article, one tree cut down can produce 173 reams of paper. A total of 7 million reams of paper is equivalent to 12 pounds of CO2 being released into the atmosphere. 

Trees are very useful to man. They support the life old living things. Trees are needed for making paper, furnish and houses. They are used in everything. When w breathe and burn, we produce carbon dioxide. Trees replace this carbon dioxide with oxygen. The green leaves of trees absorb carbon dioxide and break it up into carbon and oxygen. The leaves keep carbon and release oxygen for the use of living beings. Trees prevent drought and floods. Man has cut down trees in large numbers and he is cutting more and more trees. Man must stop cutting more trees, otherwise he will suffer greatly
