Land certainly has different values from different perspectives. From a personal view, it is something that you personally own and can do what you will with. However, from a public view, some amount of land also has to be used to support infrastructure. When these two views collide, as we see in the article, I think that it becomes very difficult to find the right course. Our society is supposedly built on not putting the group before any one individual, but at the same time that individual will still be consuming some of the energy that becomes available. In light of energy use, I think that it is fair to ask someone to have a pipeline go through their land. However, I also believe that it should be made as safe as possible, and that the individuals sacrificing their land should get full recompense for the lost property, plus the possible decrease in property value. I believe that engineers come into this equation by studying and implementing ways to minimize loss of property, maximize safety, and plan routes so that the least possible impact is felt. If full recompense is given, safety is maximized, and impact of the gas line/project is minimized, I believe that it is ethical.
