The environment of Florida in the United States yields an array of land and marine life in a mild subtropical climate. This environment has drawn millions of people to settle in the once rural state over the last hundred years. Florida's population increases by about 1,000 residents each day. Land development and water use have transformed the state, primarily through drainage and infill of the wetlands that once covered most of the peninsula.
Much of the state of Florida is situated on a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Spanning two time zones, it extends to the northwest into a panhandle along the northern Gulf of Mexico. It is bordered on the north by the states of Georgia and Alabama, on the west, at the end of the panhandle, by Alabama. It is near The Bahamas, and several Caribbean countries, particularly Cuba. Florida has 131 public airports, and more than 700 private airports, airstrips, heliports, and seaplane bases. Florida is one of the largest states east of the Mississippi River, and only Alaska and Michigan are larger in water area.
