Problem: For this assignment, you will be considering how we can meet sustainability goals while dealing with infrastructure from the past. We have cities which were not built according to the principles of sustainability, dams that provide clean energy while creating other environmental and social problems, then there are pipelines which carry crude oil and natural gas - both fossil fuels which need to be phased out. Your task is to comment on what you think we should do with this infrastructure over coming decades. What should we continue to use, seeing as it has been built, what should we retrofit to make it more sustainable, and what should we just outright dismantle? Need Assignment Help?
