3. Population Growth of Florida and the effects on the physical environment ? Today, 900 people move to Florida daily; 39 million people vacation here some years; 12 million come in winter's dry season as water supplies naturally drop. Florida's daily population increase of 900 residents creates new demands to supply 200,000 more gallons of freshwater every day. Added square miles of building and paving reduce rainwater penetration into aquifers, the water-bearing layers below ground that store water that wells may tap. When freshwater supplies go way down, however, saltwater can intrude, with dire consequences both for water supplies and the ability of soils to grow plants. Humans, of course, cannot drink saltwater, and it can destroy plumbing appliances.
