Providing a sustainable city can be "reduce, reuse and recycle". I believe there is a lot of other ways we can help to provide a sustainable city. The first step is to start renewal in "urban areas". Another word for "urban areas" is the "hood". For me personally, having a lot of family growing up in these areas there were no local grocery stores with healthy foods and fresh vegetables. There were liquor stores on almost every corner, these are called "food deserts". Meaning this is where the funding is going, and the unhealthy foods are the easiest to get. With providing more grocery stores and more clean, nice roads the population in cities might potentially grow. Causing us to have another thriving cities. There are so many things we can do to sustain and thrive a city, starting with these areas that don't get much attention.
