Essay on 'trees are precious,I will protect them'

Answer»

re most valuable and important source of life on the earth. They are very critical to the healthy and vibrant communities on the earth. They benefit all the living things on the earth in some direct and indirect WAYS. Everything on the earth connect to each other and running according to the nature’s balance, if any disturbance occur to it whole environment may disturb and harm the lives on earth. Plants protect us from many natural disasters and nourish our lives in many ways. They keep our environment clean and earth green so, we are also responsible to them and try our best to protect trees. Large and mature trees are more BENEFITING in nature than smaller ones as they capture more carbon, filter green house gases at high rate, capture more storm water, provide big shadow and combat urban heat, reduce energy use and many more, so we should not cut them even in emergency.Benefits of TreesHere I have mentioned some real benefits of the trees which help you to understand that why trees should not be cut however need to be planted time to time.Mature trees help us to combat the climate changes by refreshing air and absorbing green house gases as they are the main source of climate change.Trees helps in air cleaning by refreshing the air as they absorb all the odors and pollutant gases in the environment.An acre of mature trees may provide required oxygen to 18 people PER year.Trees help in combating summer heat as well as low winter temperature.Trees are best energy conservation and global warming management technique as they reduce the need of summer air conditioning by up to 50 percent.They save water by SLOWING down the water evaporation from ground through their shadow.Trees are natural water filter and play great role in preventing water pollution by allowing water to flow down to the earth below TREE thus prevent rainwater to carry pollutants to the ocean.Trees prevent soil erosion by holding large amount of soil to one place.Trees provide us a strong shield to get protected from the ultra-violet rays and thus from the skin cancer and other skin disorders.Trees are good source of foods (like fruits, vegetables, etc), shelter, medicines, economy, etc.Trees have good healing property among patients having any health related complications like children with ADHD if they have direct exposure to the trees and nature.Trees are good source of identifying seasons, they reduces violence, and create economic opportunities to people.Trees are best teacher who never talk but shows everything. They are also best playmate of the kids.They are good example of unity in diversity.Trees are good source of reducing noise pollution, water pollution, air pollution and soil pollution.ConclusionBy seeing all the benefits of trees mentioned above, we can completely understand the value of trees in our lives. Thus we should not cut trees, we always oppose the cutting of trees and forests, we should promote more tree plantation in the human crowded area, and motivate common people to save trees.
