Aww, your daughter is so adorable. I totally agree, the city life has caused us to lose touch with nature. Having more green is 100% a necessity, and although I have no evidence I can point to, I know that interacting with nature, even in such a small way as starting a garden has a positive effect on mood and stress, well, it does for me anyway. I wish all town planners thought the way you do, it would certainly make our cities more beautiful if nothing else.
