This week, watch The Day After Tomorrow. The disaster depicted was "natural", but obviously hyperbolic. This week, your task is to find an example of a disaster that was caused by humans doing something that they shouldn't have been doing- or something they took too far. What happened? Did the scenario start out as a bad idea? Did anything change as a result of the disaster? How does this event relate (or not relate) to The Day After Tomorrow? Please place a link to your example at the bottom of your post.
