Tree in a city
Many cities and urban communities around the world are beginning to make improving their “green infrastructure” a priority because they understand how vital trees are.
Trees provide benefits that improve the quality of city life, making urban environments more liveable and sustainable for everyone. Trees also help mitigate the negative outcomes that come with the modernisation of facilities, businesses and services in our communities, such as pollution, heat and density.
But most importantly (and often overlooked) is that trees can actually produce positive returns for the economy, especially when they are well taken care of.
To provide some insights about the true value of urban trees, we’ve prepared a list explaining their importance, why cities need trees and the different solutions you can utilise to help them thrive for a long time.

   Trees make cities more visually appealing.
   

Urban trees provide an aesthetic touch to our streetscape. By adding colour to grey spaces and separating various urban fabric elements (meaning pedestrians, motorists, buildings, parking lots, etc.) from one another, they transform busy cities into more harmonious and pleasing environments.

2. 
   Trees improve air quality in cities.
   

With growing populations and advancing industrialisation, air pollution is an unavoidable problem in developing cities. Fortunately, trees can minimise the toxic levels of air by drawing out carbon dioxide.
A mature tree alone can absorb up to 48 pounds of carbon dioxide, while trees within street proximity absorb 9 times more pollutants than those planted far from each other. Research also shows that ozone is improved by 3% to 7% every time urban tree canopy increases by 10%.
