that's a crazy story. you can't really look at it as men destroying the environment though, that was a freak accident, it's not like intentionally clear cutting a rain forest. for all we know the environment was changed for the better,
"Within two days, what had previously been an eleven-foot-deep freshwater body was replaced with a 1,300-foot-deep saltwater lake. The lake's biology was changed drastically, and it became home to many species of plants and fish which had not been there previously."
From 11' to 1300' ! that's a lot more room for animals to live and grow in
