At Prince William Sound (remember Valdez!) the single most important issue was the environment. I am so anal retentive about this fiasco that I have not bought a drop of Exxon product since that day and vow that I never will.
In Tuesday's horrific event it's my guess that the environment is so far down the list of priorities that I think it will be a long time before that becomes the focal point of concern. I'll refrain from comment on the state of waters surrounding New York City, but one could say that their present condition may lower it even further on the priority list.
You're right though, it is a valid concern, the Hudson is a primary breeding ground for the striped bass and an important estuary for many important species - but it very well may be a concern for another day.
