Safety can make the city of Philadelphia a better place by creating a lively environment, bringing peace to communities and keeping crime rates low. As a community everybody has to understand boundaries. People form boundaries by identifying what is private and what is public. For example, Jacobs demonstrates to readers how sidewalks and driveways are different but both contribute to safety within the community. Sidewalks are considered as public domain while a driveway is private property. People are held accountable for keeping their areas safe and to do so you have to be aware of your surroundings. Businesses contribute because they result in continuous activity where people can watch what goes on around them. "People must take a modicum of public responsibility for each other even if they have no ties to each other." (Jacobs,82) Parks are not utilized correctly and they deprive the community from the potential of becoming a better place.
