The sea and the rivers held many resources, but to exploit them required the development of super craft to navigate waters that were often stormy and rough. The forests were rich with game and many edible plant foods, but the vegetation of much of the area was so dense that land travel was extremely difficult, and large parts of the heavily forested foothills and rugged mountains were unsuitable for human settlements. Villages instead were located along the rivers, on the shores of bays and lowlying offshore islands, and occasionally even at sheltered locations fronting on the open ocean. It is estimated that the Northwest Coast of the 140039。s population in order to demonstrate that the environment could support many people trade with Mexico was of great importance environmental problems were likely to arise many people had migrated from Mexico to the area The city is a global phenomenon. It is also a regional and cultural variable. Even 4 within the seemingly homogenous North American cultural realm, the city shows subtle but significant differencesnot only between older eastern and newer western United States cities but also between cities of Canada and those of the United States. Although the urban expression is similar in the two countries, it is not identical, and the truly “North American” city is more a myth than a reality. The Canadian city, for example, is more pact than its United States counterpart of equal population size, with a higher density of buildings and people and a lesser degree of suburbanization of populations and functions. Spacesaving, multiplefamily housing units are more the rule in Canada, so a similar population is housed on a smaller land area with much higher densities, on average, within the central area of cities. The Canadian city is better served by and more dependent on mass transportation than is the United States city. This dependence gives form and structure to the Canadian central city, qualities now lost in the sprawling United States metropolis, whose residents view the central district as increasingly less central to their lives. Since Canadian metropolitan areas have only one quarter the number of kilometers of superhighways per capita as United States metropolitan areas and at least as much resistance to constructing more suburbanization of peoples and functions is less extensive north of the border than south. It is likely to remain that way. Besides these physical differences, Canadian United States contrasts are also apparent in their cities39。s?
