Trees are Earth's longest living species, For humans and the earth, trees play a crucial role.The streets, parks , playgrounds and backyards are lined with trees which create a peaceful atmosphere. Trees increase our quality of life through urban planning of natural elements and habitats.
The bulk of the population of the world lives in cities. The UN General Assembly developed UN Sustainable Development Goals to enhance the quality of life of people to meet the needs of people in a changing world. These broad priorities outline our times' greatest challenges. An efficient strategy to help achieve these objectives is planting and maintaining trees, especially in cities where the majority of the population live. This paper is a critical study of the advantages of trees. Via air emission, stress reduction, encouragement of physical activity and promotion of social links and culture, trees promote health and social wellness.
Researchers have found that, because of the particles they extract from the air, trees and forests save an average of one life per year per region. A research in the Journal of Preventative Medicine showed that when they lived in areas where trees had vanished, people suffered more deaths from heart disease and respiratory disease. Owing to the oxygen they provide to other living organisms, trees are sometimes referred to as the "lungs of the planet."
Trees sequesters carbon (CO2), which minimise total greenhouse gas concentration in the atmosphere. A cooling effect of ten residential air conditioners 20 hours per day can be created by evaporation of a single tree.
Trees play an important role in rainwater collection and reduction of the probability of natural disasters. Their complex root systems serve as filtres, contaminants are removed and water absorption into the ground slows down. This prevents damaging erosion of waterslides and decreases the chance of over-saturation and flooding.
There are a large range of birds, animals and insects that call home trees. A diverse variety of wildlife from the lower levels up to the very high canopys is present in different levels and canopies of trees. Farmers of forest garden also also use trees to create garbage to help bees pollinate and to harvest sweet melon. We are losing species at the moment at an alarming rate, so the biodiversity room is vital to our planet 's future.
The Amazon, the largest rainforest on earth, has around 390 billion plants, three times as many as the stars in the Milky Way.Unbelievably, about half the Amazon's rainfall is provided by these trees. Trees serve as giant pumps in the Amazon and elsewhere, drawing water up through their roots and releasing it through leaves, a system known as transpiration. One tree will raise from the ground about 100 gallons of water and release it into the air every day! Twenty-two billion tonnes of moisture are released by trees in the Amazon every day, seeding the clouds with rain.
