If there is any silver lining to the mass destruction brought by Hurricane Sandy, it might be a renewed focus on the importance of infrastructure, and just how much our current systems -- of transit, energy, buildings, and much more -- are outdated and susceptible to another disaster. Government officials like New York's Governor Andrew Cuomo have spoken about the need for new protection, such as flood barriers. This is an important step, but is not a replacement for infrastructure upgrades that could stand up to the kind of harsh weather that America experiences more and more.
