THE LAST GASPSUSTAINING LOS ANGELES FOR A
BREATHABLE FUTURE
Zach Rieck
WHY LOS ANGELES??
• Los Angeles serves as a “worst case scenario” for many other urban areas
• Many natural obstacles working against it
• City has worked toward many solutions and failed
IT HAS ACTUALLY GOTTEN BETTER!!
• Data shows that the “worst” smog occurred in the ’40s
• Reasons: lack of knowledge, diesel buses, poor regulation
• This ISN’T to say the air is good now!
• There are actually mountain in LA!!
MODERN CONCERNS
• Urban heat island effect
• Runaway population growth
• Ethanol : Not as clean as we think?
HEALTH RISKS
• Air quality has historically reached levels where masks were necessary
• Elderly and people with respiratory diseases faces potentially deadly consequences for breathing
• Children may develop respiratory disease
WHAT CAUSES THE SMOG
• Natural topography causes the basin inversion effect (similar to what happens in Salt Lake Valley in winter)
• Large car emissions due to a poor public transportation system
• Relaxed emission standards
HOW IT CAN BE IMPROVED
• Investing in an affordable, practical public transportation system in the area
• Using cleaner, renewable energy that doesn’t worsen the smog as much
• Creating stricter emission requirements and harsher consequences for exceeding these standards
“THE GOAL”
• Efforts to improve LA’s smog can be applied to other cities with pollution issues
• LA is not one of a kind
• Biggest faults are the same as other cities
