  taller buildings or by filling in vacant land
• 2. outwards into the fringe area around the

• since density is lower in the areas of urban
  sprawl, services are farther apart
• increases the use of the car
• increases the impact on the environment
• leads to a loss of farmland
• taxes are high because it is expensive to provide
  services (schools, water, sewers, etc.)

• developers is the term we apply to people who
  build new residential, industrial, or commercial
  areas
• often land developers buy the land many years in
  advance and let it sit idle
• these people are called speculators
• buying and selling the land pushes up the value
  of the land and encourages more farmers to sell
  their land
