I’ll add that I dabble a little in the municipal politics level because of my interface with the aldermen, and frankly, political direction is huge. The ability to understand that, even if you are very interested in transit, transit is about livability. People walk to transit. You want walkability as well as that transit.
Everything that these gentlemen said about what trees add to a city, you could take the next step and say that parks add to a city. Whether you are walking on a green street to go to transit, whether you are changing the fabric of a playground that you take your kids to, whether there is shade and sun, the political direction at every level is very important.
