Why are these variables important to measure?

Tree Cover Canopy

Trees provide many benefits to human health. They purify the air by filtering out ozone and particulate matter. Additionally, they can also help mitigate high air temperatures through the provision of shade as well as evaporative cooling. Trees filter pollutants out of water and can help regulate water quality and serve as a form of flood and storm water control. Lastly, trees can improve mental health and add to the aesthetic quality of a neighborhood.

Measuring the percentage of tree cover in an area highlights which neighborhoods are able to enjoy the many benefits that trees can offer.
