Wikipedia says, "Miami is a major center and a leader in finance, commerce, culture, media, entertainment, the arts, and international trade. In 2008, Forbes magazine ranked Miami 'America's Cleanest City' for its year-round good air quality, vast green spaces, clean drinking water, clean streets and city-wide recycling programs. Downtown Miami and South Florida are home to the largest concentration of international banks in the United States, and are home to many large companies, both nationally and internationally. For more than two decades, the Port of Miami, known as the 'Cruise Capital of the World,' has been the number one cruise passenger port in the world, accommodating some of the world's largest cruise ships and operations, and is currently the busiest in both passenger traffic and cruise lines."
