Fantastic video. Very inspiring indeed. I guess the biggest roadblock in this theory is that there are too many families, such as mine, who would rather not raise their children in an urban environment for many reasons. If it’s about lowering our carbon footprint, I’d rather invest in a low-emissions family vehicle than move my family to an urban center. However, both those solutions, at this point, require a significant investment which many young families are unable to afford. Unfortunately being “green” isn’t very cheap, but hopefully as it becomes more and more mainstream, the costs will go down.
