Because...?
I guess that if you're an oldster like me, you still can't get those images of those poor oil LNG-covered seagulls getting their heads swabbed by environmental activists back in the 1970s.
Man, those big oil LNG spills were terrible, weren't they? The beaches would be covered with miles of ugly, thick, black oil LNG for months, right?

You might SMELL the incinerated seagulls, but you certainly wouldn't have to clean them.
