Disasters tend to bring out the best in people. Kindness, generosity, and goodwill are all easily found when people selflessly give of what they have to help those in need. Unfortunately, the opposite is also true. Stress, fatigue, and fear of the unknown play a large role in prompting people to do things that they normally would not do. And this human element is as much an issue as the disaster itself and it is more so in crowded areas. The Census Bureau reports that urban areas account for more than 80 percent of the U.S. population and growing. As more people choose to live in crowded areas, the need to consider other people becomes a larger aspect that needs close attention as they prepare.
