[Source: Casey Newton, Arizona Republic] — Great global cities of the future must make sustainability a top priority, Chicago Mayor Richard M. Daley told Phoenix residents on Tuesday as part of an Earth Day event. “Cities are no longer enemies of the natural environment,” Daley told about 200 people at a luncheon at the Phoenix Convention Center. “They’re leading the way in preserving and protecting it.”
The luncheon was part of Valley Forward‘s fifth-annual Livability Summit. The summit included a series of speeches and discussions with the theme of “Healthy Living in the Desert.”
Daley, who has served as Chicago’s mayor for almost two decades, described a series of efforts the city has made in recent years to improve the environment in Chicago, its suburbs and beyond. The efforts include rooftop gardens on high-rise buildings that lower temperatures in the summertime, allowing them to be cooled with less energy. [Note: To read the full article, click here.]
