wow i'm thinking how things have moved on, i suppose historically people have migrated and created infrastructure based on the needs of their communities ie the availability of food or work or opportunity, even longer ago based on protection, as villages grew around fortified positions that they could run to in times of need,I guess now in more modern times without the need to hunt for food and the governmental protection we all tend to take for granted things have almost reversed , instead of mass population movements going in search of work , global companies now seek out the poorer countries that provide cheap labour and in turn that helps those countries develop their infrastructure, the interesting thing though is that there is now also a science behind the development of infrastructure and I guess it goes largely unnoticed by most as we mainly just expect it to be there now, whereas in the past it was something born from necessity that people had to construct just for survival, advancement is a wonderful thing and has it been for the better, id say absolutely \o/
