CHAPTER 1 TREES IN CITIES: THEIR IMPORTANCE AND CHALLENGES [1.1] Trees are Fundamental to Cities and to People In the past, many people viewed trees in cities as ‘nice to have’ amenities for largely ornamental purposes. However, we now recognize that trees in cities are fundamental to human well-being and to the functioning of the natural environment on which we all depend. [1.2] Pollution and Flooding Reduction Trees in cities provide a healthier environment for everyone. They absorb carbon dioxide and other gases from the air and produce oxygen. Trees improve air quality by trapping dust particles; levels can be reduced up to 60% on tree-lined streets compared to those without. [1] Trees can act as a sound barrier, absorbing noise in built-up areas. Trees and their root systems absorb water, reducing the potential for flooding. A typical medium-sized deciduous tree can intercept over 10,000L of rainfall every year. [1] Trees also help prevent riverbank and soil erosion and help filter out some water pollution before it reaches rivers and streams. [1.3] Human Health and Well Being Trees have a positive impact on both physical and mental health. Scientific studies have shown that the presence of trees boosts the immune system, reduces stress, improves mood, lowers blood pressure, increases ability to focus and energy levels, accelerates recovery from surgery or illness, and improves sleep. [2] Trees also support better health by creating a positive backdrop for outdoor activities, encouraging people of all ages to walk and cycle within their neighbourhood. Trees are also important in allowing children to interact with nature and develop their motor skills. Trees stimulate the senses and connect us with our surroundings by marking the changes of seasons with flowers, scents, and colourful seasonal transformations. 1.
