It is often said that people are afraid of the unknown, which amounts to say that they are afraid of change. Change means moving from a world we know to a world we are not familiar with yet. A world that is different.
Yet, change is the only constant of life. Change is life itself. We often spend a lot of time and energy trying to keep our lifestyle and our living environment always the same, but our purpose is always eventually defeated. Since things must change, let them change in a positive way.
Recently, as Alex Steffen pointed out, in New Orleans: Everything Has Changed. The people there, the inhabitants and the authorities, have mostly ignored the fact that things couldn't always remain the same. What just happened there was apparently doomed to happen. Since the authorities were not prepared to make drastic changes, nature used human's own folly against them and forced change on them.
