28、s the automobile has had on the world is the huge increase in the amount of surfaced roads.With increased road-building came loss of habitat for wildlife.Loss of rural areas and agricultural land to pavement has also been extensive.The quality of roads was also improved.Roads were paved with asphalt

29、,and roads with more than one lane on each side became commonplace.,Unit 9 Automobiles,Background Information,Background Information,Technological changesThe assembly line and other methods of mass production were developed when American businessmen began seeking ways to build more automobiles at a
