Most of the South Florida metropolitan area obtains its drinking water from this aquifer. As a result of the aquifer, it is not possible to dig more than 15 to 20 ft (4.6 to 6.1 m) beneath the city without hitting water, which impedes underground construction. For this reason, the mass transit systems in and around Miami are elevated or at-grade.
Most of the western fringes of the city extend into the Everglades, a subtropical marshland located in the southern portion of the U.S. state of Florida. This causes occasional problems with local wildlife such as alligators venturing into Miami communities and major highways.
Tourism is also an important industry in Miami. Along with finance and business, the beaches, conventions, festivals and events draw over 38 million visitors annually into the city, from across the country and around the world, spending $17.1 billion. The Art Deco District in South Beach, is reputed as one of the most glamorous in the world for its nightclubs, beaches, historical buildings, and shopping. Annual events such as the Sony Ericsson Open, Art Basel, Winter Music Conference, South Beach Wine & Food Festival, and Mercedes-Benz Fashion Week Miami attract millions to the metropolis every year.
