Aren't you getting tired of doing this? It's bad, it's still getting worse, it can't be fixed (the exclusion zone, I mean). Yes other industrial accidents killed more people, faster. Yes, other industrial accidents also create no-go zones. So what? If you get beat up, you say "it's OK because the other gang down the street just murdered someone"?
Get over it. I know you're personally invested in this but... really. The Nile ain't just a river in Egypt, you know?
