With New York's skyline on the rise, Fast Company says that there will no longer be sunlight on the streets of Manhattan by 2020 (unless you can afford a rooftop penthouse). Thirty-four skyscrapers 700-feet and taller are currently in-progress or being proposed, adding to 41 that already exist. This may seem like a lot, but as Fast Company also points out London has 230 new towers over 20 stories planned. See National Geographic's "The New New York Skyline" illustration for a closer look.
