Understanding Human-Caused Disasters

The video explores three major human-caused disasters: the Bhopal gas tragedy, the Chernobyl nuclear accident, and the Deepwater Horizon oil spill. Each disaster is analyzed in terms of its causes, consequences, and the lessons that can be learned to prevent future occurrences. The video emphasizes the importance of understanding the science and engineering behind these events to avoid repeating past mistakes.
