Explain why new technologies are making physical features less of a challenge when creating and changing national boundaries

New technologies make physical features less of a challenge when creating boundaries. Many new technologies have been created to overcome these barriers. For example, a mountain range was once an impassable barrier. Now we have the technology that allows us to fly over the mountain or tunnel through it. We have created heating and cooling systems that allow us to live in extreme climates, such as desert or arctic regions. We also build dams that allow us to live near water sources or store water where it is scarce. These technologies allow people to create barriers for political reasons, rather than because of physical challenges.
