We enter a better kind of urban jungle on this episode all about the science and economics of trees in cities -- way more interesting than you might think at first. Yep, there's a big economic argument for more trees in our cityscapes. Our guests here apply scientifically backed dollars-and-cents appraisals to the trees that line our streets or green our downtowns. And they discuss tools you can access to tally such values where you live. And, yes, we also discuss the much-harder-to-quantify relationship that humans and trees have shared since the dawn of man -- and what that means for city neighborhoods lacking in greenery. A lot to think about -- and surely a few surprises -- in the episode.
