12. 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)

13. Disposal Automobiles contain many harmful chemicals and lead that could hurt the environment. 65 % of the vehicle may be recycled http://investors.hexagon.se/index.php?p=press&s=detail&afw_id=1065356&afw_lang=en http://www.ineospolyolefins.com/Markets/ConstructionDurable/CarFuelTank.aspx http://www.wired.com/autopia/2007/06/up-to-450000-ch/

14. Conclusion Made life more mobile Far distance Trying to make drivers safe Faster cars Trying to make it safer Continue to Develop (design & efficiency)
