But why so many cars in the U. S. ? • • Large land area Large population American Culture: Individualism Fordism: Prosperity through mass production and mass consumption: Assembly Line = Affordability • Led to the domination of the Auto Industry in the early 20 th century • History of affordable gas ? 6

U. S. : Railroads used to be #1! • Most dominant form of transportation in the U. S. until after WWII • However, by the end of WWII, gas was cheap and so were cars • “Everyone can have a car in their driveway for $500”—Henry Ford • With economic boom after the war, people had the $$$ for a car…and a house. • But is there more to the story? 9
“The Streetcar Conspiracy” • 1921: General Motors lost $65 m 1921: • 90% of all trips taken by rail • Only 1 in 10 Americans owned a car • 15 billion rail passengers per year • Most towns of over 2, 500 had a rail system • GM formed a new conglomerate composed of: – – General Motors Firestone Rubber Co. Standard Oil Co. Phillips Petroleum 10 John D. Rockefeller (Standard Oil)
National City Lines • • • New Company Created: National City Lines was to “buy out” 100 major rail lines from 1936 -1950 Through a variety of means, National City Lines “persuaded” the railroads to convert their trains to buses National City then dismantled and decommissioned the trains and rails U. S. Highway System began in California— first place where railroads were bought End of the railroad era in the United States 11
However… • Many believe National City Lines came in after the trolley and rail system was already in trouble • Great Depression • Case went to court in 1948: – GM found guilty of conspiracy – GM had to pay a fine of $5, 000 12
North Shore Line: Chicago to Milwaukee • GM helped acquire and dismantle the $50 million North Shore Line • Was the fastest electric service in the world • Milwaukee to the Loop • However, was in dire financial straits (had filed bankruptcy several times) • GM also purchased and scrapped the street railways serving Minneapolis-St. Paul. 13

Questions… • Is it too late to revive the railroad? Should we revive the railroad? • Every other highly populated core country has a significant passenger railroad system—not us. • Would you use a rail system if one were to become available? • Railroad vs. taxis: MSP to downtown $2. 00 $36. 00 • More ecologically friendly and cheaper 16

High-Speed Rail • • • Competes with airlines in Europe, Japan Fewer delays, easier through security More eco-friendly Airport hassles: more likely to catch on? Or same old story? 19
Perhaps not too far off? 20
Back to cars… • Post-WWII: U. S. economy BOOMING! • Women in the workforce: no longer only option being the “farmer’s wife” • People making $$$ = More demand • More demand = More production • More production = More people moving off the farm and into the city • But cities were dirty, cramped 21 • Birth of suburbia
Not only was the economy booming… “Baby Boom” • More people = More resources 22
The Suburbs 23
Suburbanization • • • A new “neighborhood” City conveniences without the city Led to the decline of the city Loss of “neighborhood” / community More individualistic Automobile dependent (shopping, banking, school, etc. ) 24
Conflict: Urban Sprawl vs. the Environment • Encroachment into Wilderness - Animal conflicts - Plants conflicts • Environmental Impacts - Water Pollution / Depletion § § Overwatering of land (Las Vegas grass ban) Golf courses: chemicals Depletion of aquifers Wetland / natural habitat destruction - Smog / Pollutants from vehicle emissions - Lack of exercise (car) 25
Las Vegas • • One of the fastest growing cities in the U. S. over last 10 years…until recently What is its carrying capacity? Where would Las Vegas be without extreme non-ecological efforts to support the city? One of the most ecologically “wrong” cities in the world (and Phoenix) 26
Dubai: World Islands Palm Islands 27
Hoover Dam • In today’s $$$, would cost approximately 2/3 of a billion $$$! • Supplies power to So. Cal, NV, AZ, elsewhere • Lake Mead created from damming Colorado River • Without dam, Las Vegas and L. A. could not exist as they do • Is that good or bad? 28

Why? The auto industry 42

Speaking of the automobile… 47
Rudolf Diesel (1858 -1913) "The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in the course of time as important as petroleum and the coal tar products of the present time. " After his death, the Diesel engine was marketed that it only ran on petroleum based products and his great ideas of a clean burning engine died with him. 48

Which fuel is greenest? 51
Cellulosic Ethanol PROS: • Not a specific crop • Made of yard waste: weeds, wood chips, stems, etc. • No competition with food production • Abundant in North America • No need for pesticides CONS: • Tough to market • Infrastructure not set up to handle this type of fuel • Land availability Switchgrass 52
Tequila Sunset: The Ethanol Boom Mexican farmers burning agave fields and replanting them with corn Wednesday, 27 August 2008 Mexico without tequila? It seems a far-fetched notion but the country's farmers are shunning the famous agave plant because of poor prices and switching to profitable crops. Savour that frozen margarita in your hand, for soon you might not be able to afford it. Mexico's tequila industry is about to become the latest victim of America's growing thirst for ethanol. Soaring demand for biofuel has sent global commodity prices through the roof, prompting farmers of blue agave, the cactus-like plant from which the country's national spirit is made, to move into more lucrative cash crops such as wheat and corn. Picturesque plantations of agave…are being replaced with orderly rows of corn, a crop now selling for a record 18 cents per pound, as US consumers from across the border seek respite from the soaring oil prices. Global food price rises have also seen the cost of another rival crop, beans, rise by 60 per cent in the past six months to 59 cents per pound. By comparison, agave, which in 2002 was worth more than 80 cents a pound, is now retailing for less than two cents. As a result, many farmers of agave…are taking the difficult decision to let their over-ripe plants turn brown in the desert sun, claiming it is no longer economically viable for them to bother with the annual harvest. "Corn is where the money is now, " one large-scale farmer, Miguel Ramirez, told USA Today. "I'm going to get out of agave completely. " Martin Sanchez, director of agriculture for Mexico's Tequila Regulatory Council, added: "We don't have numbers but we know it is happening: people are abandoning their fields of agave and flipping over to other crops.
