These sites represented various organizations that are trying to better urban living conditions through increased interaction with greenery. The studies that correlated the benefits of greenery to less crime, greater concentration, less domestic violence, are understandable and very interesting. However I would have liked them to be a little more specific - the vagueness made it sound less credible. Overall the studies did make a lot of sense, because they all harkened back to nature's calming effect. I really value the work of organizations that seek to show nature to innercity children. Beyond establishing self confidence and leadership, these outings establish a relationships with outdoors. It is often the children who played in nature that grow up to care the most about the environment.
