Causes of Air PollutionCauses of Air Pollution1. huge population = lots of cars2. high elevation--less oxygen so fuels
don’t fully burn--higher level of gases that harm eyes,
lungs, & the heart
3. Sierra Madre mountains surround city & trap in polluted air

SolutionsSolutions◊ To reduce air pollution, the city
promotes public transportation (buses, subway).
◊ The city is also testing buses that run on cleaner burning fuels.
◊ new restrictions on car use◊ workshops to teach people about
the environment
