But we’re concerned that both BP and our federal government seem eager to declare the crisis over even as oil continues sullying the habitats on which the Gulf’s wildlife and seafood industry depend.

While Wednesday’s NOAA report touted that only a quarter of the oil is in marshes or still on the surface, it says another quarter was naturally or chemically
