I love walking, the best part about it is observing your surroundings. I grew up in the city and i've always hated subways and busses. At the time I wasn't really aware of how environmentally friendly/unfriendly these actions were, but I was very aware that being underground and sitting in a vehicle waiting for it to take me somewhere was just depressing. It's so much nicer to just take a walk and enjoy the outdoors. There are a lot of buildings in the city that inspire environmentally friendly habits such as solar panel roofs, minimal glass, cutting down unnecessary light pollution, etc. However, the vast majority of Manhattan still has a very long way to go. NYC is one of (if not the worst) polluters in the nation. Seldom do we get a clear sky, light pollution is often abysmal... That being said, I am proud of my city in regards to the fact that I am seeing so many more tress on the streets than I've ever seen before. Central Park used to be the only actual area with trees, i'm starting to see them everywhere now. I'm glad to know that the city is putting in an honest effort. The next step we need to take is eradicating times square off the face of the Earth. Not only would it help the planet, it would improve the mental state of thousands of locals that actually have to live there/commute and walk through that heaping pile of garbage, lights, tourists, pollution, and anything else you can think of that will give you a migraine.
