Environmental impact
Contributes to global warming (CO2) Ozones breaking down Acid rains Summers more hot because asphalt
roads absorbs sunlight Cutting down more nature Causing air pollution (80% from
automobiles in urban areas)
Disposal
Automobiles contain many harmful chemicals and lead that could hurt the environment.
65 % of the vehicle may be recycled
