extent of the beaches. Recent hurricane and tropical storm
activity increased coastal erosion.

Electrical usage as a total continues to climb. Reductions in 2004 were due
to electrical outages associated with tropical storm power outages.
Power saving appliances, light bulbs and other practices may to preventing
a greater rise in per capita usage.

Solid waste generation continues to climb. Slight reductions may be due to
the slow down in construction activities.
Per capita usage continues to climb.
Short Term Challenges for Broward’s
Environment
• Poor Economy
– Possibility of reduced compliance with
environmental regulations – Too costly to “do the
right thing”.
– Businesses close and leave behind environmental
problems
• Growing population
– More waste generation
– More energy and water use
– More cars impacting air quality (greenhouse gas
emissions)
– Less land and habitat available
• Tourist Industry
– Ever increasing numbers come and consume local
resources
Long Term Challenges for Broward’s Environment
Climate Change presents a significant threat to
Broward’s quality of life, the health of the
natural resources and safety of the S. Florida
community.
– Sea Level Rise
•
•
•
•
Impacts coastal ecosystems (reefs and sea turtle habitats)
Erodes the beaches
Threatens property
Intruding saltwater into wellfields
– Warmer air temperatures
• Increased energy use
• Increase in infections (both human and natural)
– Changes in weather patterns
• Increased frequency and intensity of tropical storms
• Changes in precipitation
ENVIRONMENTAL ACTION ITEMS
for the CCB
• Encourage reduce greenhouse gas emissions
generated by the use of fossil fuels by:
–
–
–
–
–
improving and promoting transit;
reducing energy use;
recycling;
encouraging alternative fuel vehicles; and
increasing use of renewable energy sources (e.g.
solar and wind power).
• Follow proceedings of the Broward County
Climate Change Task Force (CCTF)
• Review and, where possible, adopt CCTF
recommendations into CCB activities
(January 2010 timeframe)
