I built a web app that allows people to help survey the trees in the cities, identify their species, keep track of their growth and help scientists to understand how trees react to climate change. With a simple formula, we calculate an approximate value of their Carbon fixation and he amount of oxygen that those trees contribute to the air we breath. It provides useful information to the local environmental authorities and raise the concern about the importance of urban forests.
