The science textbooks had to be rewritten in 2004. They used to say “ It's impossible to have hurricanes in the South Atlantic.” But that year, for the first time ever, a hurricane hit Brazil.

Questions to Think About
• How many of you commute alone
in a private vehicle?
• How many of you walk to various
locations throughout the
day (i.e. the grocery store, the
bank, etc.)?
•How many of your children can walk to school?•How many of
your children can walk to a park?
•How many of you pay more than $300 a month for utilities?
•How many of you spend 35
minutes or more driving to
work?
•How many of you drive
your children to school?•Who uses
mass transit when making
local trips?

• Rapid loss of trees in Atlanta• Atlanta’s natural tree coverage is being
removed• The impact of 1acre of trees
Georgia Tree Facts
Atlanta Transportation
• 86.1% of drivers in Fulton County drive private vehicles to work.– Dekalb – 82%– Gwinnett – 85%– Cherokee – 87.3%
• In 1990, 25% of commuters in Fulton County took public transportation to work, in 2000 the statistic dropped to 18.1%
Atlanta Transportation Facts
Atlanta Transportation Facts
• Average commuting distance – 29.2 miles
• Individuals that travel alone and do not carpool spend $16.38 per day; $360 a month
Sprawl
• Economically–Forces the government
to provide new infrastructure for a dispersed population
–FACT: the average American family spends 14%-18% of its total budget on transportation
Effects of Sprawl
Possible Solution
• Economically– Compact development
arrange new homes together so services can be provided efficiently
– Compact development provides people with the choices, instead of driving, decreasing the amount of money spent on gas. City Hall East

Effects of Sprawl• Environmentally
– Longer distance driving = increase in air pollution• FACT: air pollutants from
cars are responsible for 20,000 – 40,000 annual cases of chronic respiratory illnesses.
• FACT: The World Health Organization estimates that 4.6 million people die each year from causes directly attributable to air pollution
Possible Solution
• Environmentally– Compact
developments provide opportunities to walk, bike, or take public transit, therefore reducing air pollution Wade Green

Effects of Sprawl• Socially
– Traffic congestion takes away time from everyday life• FACT: the average
American driver spends 443 hours per year behind the wheel.
– An increase in driving means and increase in auto fatality rates
– Absence of pedestrian friendly routes decreases the opportunity for exercise
Possible Solutions
• Socially– Getting to know
neighbors increases the feeling of security
– A town center will increase civic engagement, quality of life, and community solidarity

What You Can DoFluorescent Lighting• Payoff Time : ± 3 years• Benefits• Lower watts result in lower cooling costs• $10 more for fixtures, but quickly recouped in yearly energy savings
Photovoltaic Panels (solar energy)• Payoff Time : 10 +Years• $6.50 - $8.00 per watt to install• Benefits – Reduces utility bills
What You Can DoGreen Roofs • Payoff Time : 4 to 13 years• Benefits• Reduction in noise• Prolonged life of the underlying roof membrane by protecting it from ultra-violet rays
• Extra insulation for building• Reduces air conditioning costs as much as 25%
