Trees are not only beautiful, they also provide shade and create homes for our animal friends. They may also help combat climate change.
Trees help clean the air, stop soil erosion, create new shade and even help block harsh winter winds. They play a part in cleaning the area around them by removing carbon dioxide from the air, storing carbon within the bark and soil, and releasing oxygen into the atmosphere.
Planting more trees has many benefits that include beautifying the area, providing shade to cool buildings, and most importantly improve air quality. Air quality is not only going to be improved by the trees removing carbon dioxide from the air, but in reducing the temperature, less energy is wasted on air conditioning and cooling.
Other added benefits that are also going to help urban centers include improved storm water management, lower maintenance costs on pavements, and even reduced noise reduction! (source)
